Bawb,
A true "moderator" doesn't bother with simply making a polite counterpoint to a highly offensive personal attack, instead he DELETES the attacking post and makes it clear to all that violations of the board rules are not tolerated, presuming there are impartial rules. If you don't at least make a token effort to enforce the rules, the board is defacto un-moderated.
Did Willy delete your post? Do you delete any? If you do, I can't picture just what constitutes a deletable post in your mind, seeing what you let remain.
intellectual discourse has some pretty easy to understand boundaries in civilized culture.
