I'm not desi but from what I've heard of the Memon community you have a lot to be proud of---enterprising, educated, value intellectual reasoning, etc. If you find yourself being comfortable with Memon guys I don't think that you need to look elsewhere on any sort of 'diversity' principal (though don't get me wrong, I think mixed relationships can be really awesome and are definitely within the spirit of Islam IMO.)
It's funny but my experience with my own community/ethnicity was the opposite from yours----I got so sick of hearing about football and beer and couldn't stand hearing guys use the term 'sweet.' So I ended up with a desi instead of a white boy. :)
Yes and the arabs should have stayed in middle east oh i mean S. Arabia they should not have spread the message of Islam and no one should marry from another religion let alone to a non memon or non chaudhry my goodness gracious me am i dreaming here!!! what is wrong with you people.
Its this kind of thinking which is creating problem in the world.
