Examples. Got more than 10? How many is "many"?
Just saw this. Aw, come on. Do I really have to? This is silly.
On an every day level, out of the millions upon millions of Christians there are a certain number who are extremely evil and a much larger number who...well let us say...are marginal. That's just how human beings are, Christian or otherwise.
On an institutional level I read that Armenians are telling Turks that the 1915 genocide was the fault of Jews. Don't know whether those are Christian or secular Armenians but that mentality was very common in among eastern european and near eastern christians in the late 1800's. It's what led to repeated pogroms...and was commonly the fault of local orthodox churchmen.
