While I do not know that Chaimfan should have been banned. I do understand it. Jeffguy and I both were disgusted with comments Chaimfan made regarding hanging men in the streets, raping women and then executing them, and killing little kids.
It was the comments about raping women and then executing them that were entirely disturbing. Whether or not he was "kidding" is not the issue. Rape is not a kidding issue. Raping and then killing someone is not a joke.
If this kind of speech is allowed here, then I will resign as a moderator immediately and JTF will lose me for sure. This is supposed to be a religious organization, and while I am not Orthodox I cannot fathom how anything in Chaimfan's posting remotely would be pleasing to HaShem.
