You're kidding, right? If not... perhaps you can refresh my memory on cases of Christians strapping bombs to children in order to obliterate other children.
There may have been Christians that are whackjobs, but they are also roundly denounced by the rest of mainstream Christianity. Muslims do not denounce their whackjobs. They are embraced. Because they agree. The silence of Islam writ large to the evil they spawn, is deafening.
And no, saying that Christians have not snuffed out all the bad Christians--a simple fact-- don't cut it. If you're looking for a fight, try picking one with someone who actually says the things you claim I said.
