Looks like blacks kill a lot more black worshippers than whites. black shooters. And whites tend to target other whites. THAT is your pattern.  You can dislike facts, but you can't ignore them.  But doesn't it make sense that they're usually pissed off at someone in their own community?
As to burnings, it will take more time than available to ID the perps in those cases, but the sheer number suggests a small group dedicated to the task, and even then, black churches are only slightly over-represented on a demographic basis.
Does not include the more recent SC church shooting that was definitely racial in nature, with a white shooter and black victims.
