Hmmm not in my case. I look like a desi (last time I checked my skin color was still brown), dress like a desi (love Pakistani fashion), have my natural desi hair, my husband has a dari and we eat like desis. Actually we eat like Muslims, Zabiha halal. However, we do not speak Urdu with each other. Oh and yes I wear kajal. Buy it specially from Pakistani stores here. My Nihari is killer, learned it from my dad whose an awesome cook.
There you go mixing culture and religion. Eating jhatka or halal has nothing to do with speaking Urdu. Halal/haram is not only reserved for Pakistanis.
