Christians really aren't a suffering minority, but of course it's wrong to attack the members of religious groups for what they believe.
By the same token, I recognize that some groups of Christians have been responsible for atrocities, and I'm happy to condemn the Crusades and the homophobia of institutions like the Westboro Baptist Church. That isn't "anti-Christianity", though: I believe that bigotry, rape and murder are very much the opposite of what Christianity is at its heart.
