Your comment ignores the fact that probably 90+% of US rapes and murders are committed by baptized and/or in-some-fashion nominal Christians. So I'm curious how you'd justify not deporting all these nominal Christians, too, given that this religion is so highly represented in the criminal demographic you note. Merely because they were born here? 

100% in favor of letting "Christians be Christians in Christian countries." Problem is that too many of them clearly fail at it here in the USA. You're scapegoating. It's profoundly hypocritical.
