Many xtians xtians justify child rape and genocide, possibly echoing their own preferences and hobbies, blowing away two innocent people is small potatoes.
Mean people will try to classify themselves as something just because they want a "reason" for their cruel acts. It is simple, there are extremists of every group. Politics, religons, even feminism, It doesn't mean that christianity is a bad religion at all, it just means that that man was crazy and wanted a justification for his actions.
There are some protests of extreme southern baptists that protest outside of a funeral of a soldier who died at war, and they will say things like "your son died in the war because they have gay rights in America." That sounds a bit extreme to me. See now most people from that church wouldn't do such a thing, but there are always (and always going to be) those few.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
