["Christians never beat their wives or children..."]
You won't find much support in the Christian community for wife-beating. It happens, but it's not given sanction by any Christian Church that I know of. Now tell me the same is true of mosques, and islam.
I'm sure the women being beaten by Christian men take comfort in that. "Hey, this doesn't hurt so bad, because the church doesn't approve!"
The distinction is a small one when we get down to the individual cases like this one.
People around here mention that Islam means "submission," yet seem to forget that the Bible says wives should be "submissive" to their husbands.
