I agree about the banning, but some bans have been very quick tempered. One night a young marine was banned for saying Reno investigated Clinton more than Bush did. I thought the ccomment was astute. He was banned for being a liberal. There is sometimes a mob reaction or quick trigger on these threads. All you have to do is have the wrong person cry to the moderator.
I don't know if I would have banned him under the circumstances you describe, but it is also not my call. Further, since I did not see that thread, I don't know if he was banned solely because of the circumstances you describe. Finally, I don't know if the banned poster was a young marine.
Reno investigated Clinton more than Bush did?..What a remark! The President could never have investigated the exPresident...think about it! It may be hard to take but ex President Clinton made out like a bandit and all he lost was the ability to present arguments to the Supreme Court!.... and a few bucks that he and Hillary can make up in book sales.
