Recently I was asked if I like a certain "ethnic group(Indian)" of girl. My initial reaction was sure why not, but I thought about it after and while and while I would probably not object to a casual relationship or to the bedroom, I can't see myself in a long term relationship with a different ethnic group. A fling is one thing, but taking someone down the aisle is a whole new ball game.
It might sound petty, but if you were to construct an ideal mate most people wouldn't be flipping a coin when choosing skin colour. Oh and for the nerds, no fantasy races don't count.
Edit: I'm using the adjective definition of ethnicity so it applies to race, just to clear this up as apparently there was confusion. Even tho technically race when referring to humans is really a cultural, political and economic concept in society, and it is not a biological concept.
i.e. Caucasian, Asian, Black, Hispanic etc.
