I agree. Let all the attacks stand--so everybody can see exactly what's being said by everybody. The true colors should be visible.
Stupid vulgar attacks by Mudcatters themselves can be punished by pulling the offender's cookie--but the attack should stand. Attacks by non-Mudcatters can be ignored--and should also stand. And right of self-defense should be a given. You can either ignore an attack or respond--it should be up to the individual.
