I couldn’t care less about her claiming to be a Christian - it’s meaningless really.
There are 2 aspects about this I care about. (1). I am getting more and more outraged that Christianity has become a gateway drug for neofascist extremism every time I hear one of these jerks making a big deal about being a “Christian”. (2) The hypocrisy of these “Christians” simply pisses me off. It’s obvious they ignore everything the bible says that they don’t like, so why the pompous arrogance about membership in something you don’t take at all seriously?
