I read that as reinforcing my point. Christianity was not a motivating factor, ethnic politics was; abuse of houses of worship in any culture is not unusual throughout history, subverting the trappings of righteousness to promote evil. How that promotion was manifest, I don't know; no indication AFAIK of any equivalent of "Allah Akbar" being declared during the slaughter.

Beware the rationale of "X had its bad moments, so you can't criticize Y." The current question remains: how to draw a line between the "good" and "bad" actors? lines are being drawn, and better to help draw them well before people act on them being drawn badly.
