Reread? Oh wait, I'm good at this.
"Stop deflecting, accept reality, and fix the damn problems with your religion or give it the fuck up already. I may not be talking about you, but you're part of the problem."
Saying you're not talking to all Christians, but they are STILL 'part of the problem' heavily implies you believe all Christians are problematic.
If you get mad at people for saying, 'not all Christians' then I think maybe you're offending people you don't mean to offend.
