Since I left Christianity in 2003 and became vocal about the damage religious dogma causes, I have heard things from offended believers like "Well I'm a Christian and I don't do those things, so don't blame me."
Or my favorite: "Not all Christians."
Ad nauseam.
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.
