I'm none too familiar with creating wiki pages, so apologies on that point, but I felt I had to start a discussion on this one.
I came across this particular tidbit today and was reminded of the Psalm 14:1. It's in Matthew 5:22, and the verse goes: "But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.". King James version at least.
So basically, whenever a christian brings up the Fool line, they're sending themselves to hell. I don't want to step on toes, but I think it'd be a good addition to the article.
