Sikhism does not accept GAY marriages, and Guru Arjun Dev has rejected them as scandalous.
It is worth mentioning that Guru Arjun Dev had rejected compositions (for inclusion
into Sri Guru Granth Sahib) of Madho Lal and Shah Hussain the SUFI POETS and SAINTS
because there lifestyle was scandalous as they were homosexuals. This is inspite of their
compositions been of high order. I am just quoting and I have no independent research
so please Read Reference 1. So to me it implies that such a thing has been rejected by our 5th Guru, so no question of acceptance arises.
But supporters of PRO Homosexual LOBBY point out to the fact that Maharaja Ranjit Singh
used to pay homage to samadh of these homosexual SUFI poets as RANI MORAN a
MUSLIM was devout of the SUFI poets. Some scholars point out to the fact
that Maharaja Ranjit Singh’s courtiers used to attend Mela Chiragan at dargah
of these SUFI's wearing same type of Orange clothing, and thus imply that they
approved of homosexual practices. REF[2] are attached for you to peruse and
make your own decision. But what Ranjit Singh did or did not do should not have any impact on religious teachings of Sikhs. Moreover Ranjit Singh had put his youngest wife Rani Jindan into his harem at age of 11 or 12 years of age. Other ranis had protested (now we could have pressed paedoplhilia charges against the Maharaja) as a result Maharaja had to bring back the MUKLAWA of RANI Jindan after 3 or 4 years

We had a more liberal society than we have today. Though gays and lesbians have
fraternities of their own, they are frowned upon by others. Punjabis, on the
other hand, even granted sainthood to deviants. The classic instance is of Madho
and Lal Hussain or Shah Hussain who became lovers and composed poetry jointly.
They sent some of their compositions to Guru Arjun Dev to be incorporated in the
Granth Sahib he was compiling. The Guru conceded that though their compositions
in praise of God were of high order, but their lives were scandalous. So, he
turned them down. The two were buried alongside. Every Basant Panchmi, Maharaja
Ranjit Singh rode to their grave and made offerings. They are now buried
alongside in a mausoleum close to Shalimar Garden. It has become a place of
pilgrimage for all communities.

EVERY year, on the last Sunday of March, Mela Chiragan or the festival of lamps
is held in Lahore to mark the urs or the death anniversary of Sufi mystic and
poet Shah Hussain.
Maharaja Ranjit Singh was also one of the saint’s ardent devotees. He used to
celebrate the festival of Basant at the tomb of the saint. Once Maharaja
presented basanti siropas (robes of honour) to all his sardars, employees,
munshis, clerks and vakils. Then they were ordered to reach the tomb in basanti
dresses. The infantry was ordered to dress in the same colour and stand on both
sides of the road from the fort to the tomb. Ranjit Singh’s concubine Mauran is
said to have built a mosque near the tomb of Shah Hussain. The present marble-
domed memorial of the saint, situated in Baghbanpura, near Shalimar Gardens,
does not appear to be very old. It is said that after his death in 1008 Hijri
(1599 AD), the saint was originally buried at Shahdara, situated on the other
side of the Ravi. But a few years later, the tomb was swept away by the
overflowing river. Then it was shifted to the present site. Beside the grave of
Shah Hussain, but under the same dome, there is the grave of Madho Lal, the son
of a Hindu Brahmin, to whom the saint was deeply attached. Having become a Sufi,
Shah Hussain bagan preaching in public. A Brahman boy of Shahdara frequented
these religious scenes and showed keen interest in his reaching. This attracted
the attention of the saint, who soon became attached to the handsome youth. This
attachment developed so much and so repidly that if on any day Madho failed to
come, Shah Hussain would walk down to his house. This sort of friendship was not
liked by the parents, who tried to dissuade their son from meeting Hussain, but
to no effect Desirous of separating their child from the Sufi, they proposed to
take him to the Ganges on a certain festival day. When Madho informed the saint
of his impending departure, he was much distressed and bagged the boy not to go
with his parents. However, he promised Madho a bath in the company of his
parents on the appointed day. Madho thereupon refused to accompany his parents,
who proceeded alone to Hardver. After a few day the saint asked the boy to close
his eyes, and when he did so, Madho found himself on the banks of the Ganges
along with his parents who had reached there by that time. After the bath he
discovered that he was back in his house at Shahdara. On their return the
parents confirmed their son’s statement that he bathed with them on the
appointed day. This miracle, says tradition, so much impressed Madho that he
confessed the Muslim faith and became a Mussalman. Another story about Madho’s
conversion is that the attachment of Shah Hussain for Madho was disagreeable to
the parents andcreated suspicion in the people’s mind. But Shah Hussain
unmindful of all would go to the boy’s house when he was prevented from visiting
him. Very often the parents would tell him that Madho was absent and Hussain
would return disappointed. One day when he had been refused permisssion to see
the boy, he walked down to his house for the second time. On reaching the place
he saw people weeping and wailing. On inquiry, he was told that Madho was dead.
The Faqir laughed aloud and walking to the dead body excaimed: “Get up, Madho,
why do you sleep at this hour? Get up and see I am waiting for you. “upon this,
continues the story, Madho jumped on his feet and followed Hussain out of his
parental house, never to return there again, and became a Mussalman. The love of
Shah Hussain for Madho was unique, and he did Madho Lal’s on was known all that
lay in his power to please the boy. Once, seeing his co-religionists celebrating
“Holi” and being desirous of doing the same, he bought some gulal (pinkish-red
powder) and threw it on Hussain. Shah Hussain at once joined him in the fun.
Basant or the spring festival, like Holi, was also celebrated each year by Lal
Hussain to please Madho. Madho Lal Hussain was held in great respect by the
people, and the Hindus, though they seem to have turned Madho out of their fold,
could not master their credulous beliefs in the supernatural miracle-performing
power of the saint and esteemed him just as much as their Muslim brethren. Masho
Lal Hussain died at the age of 53, a comparatively early age for a saint. His
death occurred in A. H. 1008 (AD 1593) at Shahdara, where he was duly buried. A
few years later as predicted by the saint, the grave was swept away by an
overflow of the Ravi. Thereupon Madho exhumed the corpse and carried it to
Baghbanpura, where it was buried with pompous formalities. After his death Madho
was buried by his side. Latif describes the tomb as follows:- “The tomb is
situated north of the village of Baghbanpura. There are signs of two tombs on a
high platform. One of Madho and the other of Shah Hussain, the actual tombs
being in an underground chamber. A wall surrounds the platform with a gateway to
the south. Between the platform and the surrounding wall is a space left for the
devotees to go round, - the platform being lined on all sides with lattice-work
of red stone. North of the enclosure is a tower in which is reverentially kept
the impression of the Prophet’s feet (Qadam-I-Rasul) and to the west is a
mosque. This mosque was constructed by Moran, a wife of Ranjit Singh. Lal
Hussain appears to have had friendship among the holy men of his time. He was an
intimate frien of Chajju Bhagat who, the tradition says, called him Shah Hussain
for the first time. He used to meet Guru Arjun whenever he came to Lahore.
