Maybe I have a different take on this stuff because my mom is white, but I personally don't have an issue with it.
I don't have any children, as I'm a bit too young for that now, but if I were to I wouldn't care so much if they married someone who wasn't a Jat or otherwise Punjabi. I would be more concerned with their hypothetical spouses faith/morals. I say faith/morals, because well... the faith aspect is obvious. I would GREATLY prefer they marry a Sikh, even if they were non-practicing. That said, if it is a person of another faith, I would hope they would be of some high moral standing (ie: don't drink, don't do drugs, pray/meditate every day, kind, ect.).
But as far as race is concerned, I really couldn't care less. I'm sure a good handful of peeps on here will find issue with what I've said, but lets just agree to disagree. This is just my personal opinion.
