Interesting comparison with Christianity. So if I think someone is clutching onto Christianity as basis for intolerance, you don't see the irony in throwing out "you Christian" as an insult when the person takes no offense to being called a Christian?
ETA - you're saying that my repugnance of Christianity in this hypothetical scenario is enough for the term Christian to be an insult to someone else? That's not very logical.
I have been chastised for my so called Christian beliefs and I'm not a Christian or any other religious denomination.
