Sounds like Dr Nick Nack is the most ignorant Dr of whatever I know of. He can drag his a** back across the desert and pound sand.
You're an embarrassment to all Muslims by even asking this question. Stop being so judgmental and assuming. I bet you've only heard about these 'wife swaps' from like reality shows or something.
People like you are the reason people think that every Muslim in the world hates all non Muslims and is an ignorant, uneducated piece of garbage.
