Never.
I did administrative support for an company filled with engineers that were predominantly muslim and hindu. So much so that the company had certain times of the day that they would go to a room and do their worshipping.
Also, I went to school and attended college with a few girls that wore that burka outfit.
By what I saw and heard through these experiences, there'd be no commonality for a dating/marriage relationship with anyone from the Jewish, Muslim or Hindu perception. It's all completely too weird and off the wall for me.
I befriended this co-worker, a white girl, that found some commonality with one of these Hindu engineers. She was very voiceful and outgoing with the group of us; all very nice. Next thing I knew, a few months had passed by and she became very subdued/contained/low tone of voice and even wearing typical Hindu attire at times. We were all like "what ever happened to the Susan we knew?!"
