Hinduism has reincarnation, Sikhism does not
Hinduism has Karma, Sikhism does not
I'm sorry to disagree with the reincarnation and karma issue, which has been mentioned previously in other posts.
In the Guru Granth Sahib both issues are repeatedly mentioned-
A Sikh's ultimate goal is to achieve Mukti or salvation thus escaping the endless cycle of 84 lak reincarnations.
Sri Guru Granth Sahib Ji page 4
aape bhij aape hi khaahu
Nanak hukme avhu jahu
you shall harvest what you plant
says Nanak,by the hukam of gods command, we come and go in reincarnation.
Sri Guru Granth Sahib Ji page 2
Karmi avae kapra nadhri mokh duar
by the karma of past actions,the robe of this physical body is obtained,By his grace,the gate of liberation is found.
The soul transmigrates from one body or species to another until it comes in unity with God. The hukam of God and the physical aspects of the soul in a physical life form are determined by the past and previous karma.
This understanding is made quite clear throughout the Sri Guru Granth Sahib Ji.
Luckyji, if it were that clear, there would not be articles like the following,

Getting back to the question of Sikh/Hindu adherency. I feel that if a Hindu familyfor eg. has a member that becomes a sikh, then that person will obviously respect and acknowledge both faiths and vica versa.
As a Sikh, we should respect and acknowledge all of humanity- as we are all One within the One.
I don't believe that we have the right to judge the integrity of someone claiming to be a sikh/hindu and we have no right to judge them and class them or put them outside the boundaries of Sikhism feeling that they are not good enough to be a hindu or sikh..
'Ek onkaar' and God should dictate these.
