It seems a man in California set both a Christmas tree, and himself, on fire in an attempt at a public protest. He was protesting that the local school board changed the names of "winter break" and "spring break" to "Christmas break" and "Easter break."
I tend not to fall into the victimized, "War against Christmas" mentality some Christians do. I call out silliness when I see it. If you want my opinion on this guy, glance up at that post title again.
Overreacting much? I can think of far worthier causes to self-immolate over.
