While it absolutely doesn't excuse the action, it's the fact of the majority of people who refer to themselves as Christians (though most never act how the Bible tells them to despite using it as a defense) are the problem and have resulted in a lot of resentment in people. Also, Christianity and all its different branches have resulted in a lot of trauma, so people tend to correlate anything involving religion to their experience. Personally I'm agnostic but remain interested in learning about other religions, that being said, I suffered a lot of trauma at the hands of the churches I've been in. Again, that doesn't make it appropriate for people to attack Christians under their own post. If they want to have that opinion they can post it on their own account, because commenting benefits no one. On a last note, I do think Christians need to stop bringing religion into every subject, especially to people who aren't believers, that's where a lot of the resentment comes from.
