Maybe we're talking semantics, but to me the behavior of one who is Christian would be "Christian behavior".

I would define "Christian behavior" as the behavior exhibited by Christians. Again, pretty simple.

You've got to be careful here. Just because someone is Christian does not mean that everything they do is Christian behavior. Just because their is an unequal proportion of African Americans in prison does not make criminal behavior "African American-like."

But if good Christians don't want to be associated with these people, I think they need to denounce them. Not only in their heart, but in the media.

And what makes you think we don't? You started off saying that using a qualifier was important, but you've never used one when defining behavior.
