Just before I turn in.

"Nobody was ever enlightened by NOT having his views challenged."
I agree 100% GUEST T, but there is a difference between having ones views "challenged", and being subjected to sustained personal abuse and name calling.
One can answer a "challenge" reasonably, but it is impossible to debate with someone who relies on personal insults, and the traducing of his opponent's character and motives?

Keith did swear at the person he was addressing, but he had been subjected to weeks of abuse and name calling before that.
There are few here who could have endured that treatment without occasionally "biting back".
