Might I respectfully suggest that when zapping a perp it becomes a policy to include in the thread relevant quotes from the likes of people that drive the lefties loony? That way some good can come of their pranksterism. Here's a favorite:
"A liberal is someone who has read karl Marx. A conservative is someone who has read Karl Marx and understands it."
Ronald Reagan
Or one from my father:
"The liberal's reward is self-disgust"
Any time a comment is removed from a thread a 'quoted truth' could be inserted.
Just an idea for a way to thwart the trolls...
A liberal is someone who believes it is better for a woman to be raped in an alley and strangled with her pantyhose than for her to shoot her attacker with a handgun.
