::TFD may have a point on the KKK, which I probably supported as an entry originally. The KKK was anti-black in its last two incarnations. But anti-Jewish and anti-Catholic, as well. Pro-Christian was more of a pose to solicit support. The article on KKK does not support the "Christian terrorism" as it had in the past, I don't think. It tended to be "ethnic" rather than religious.  
 ::A lot of violence in past ages was laid at religion's door, when it was actually much more national and political. While it is "neater" to lump Europe's "religious wars" into one fault, the motivation was often greed amongst the nobles. Religion was merely a "good excuse" to enlist public support.
