Re: How many sikhs have married out of Caste/Race
Then I have to ask that you not take amrit, if you cannot keep rehit maryada. You can always get a second plate, and oput the remains onto that one and distribute it like that. How do you think Langar is served? 
jasleen-ji, please correct if this is wrong also, i am unlearned.
Because, as soon as you take amrit, you take on the saroop (form) of Guru Gobing Singh, or if a Kaur, Mata Gujri. Amrit makes you a Sikh.
I think you have to understsand the peacefulness of SGGS, and bir ras (warrior essence) of dasam granth de bani. That part of amrit is part of bir ras - why share food from your own plate, with someone else who is not your brother?
Get a second plate and put the remain onto the second - but not off the same plate.
Eating off of one plate builds the khalsa into ONE body, in a sense of unity. Anybody can take amrit, assumning they can:
Wake up at Amrit Vela
Do the bani prescribed by guru Gobind Singh Maharaj, at amrit vela and sunset, and before going to sleep.
