Christians, through history, loved stoning anyone who did not agree with them or follow their beliefs. I think it would be ironic if they ended up on the other end of this.
But truthfully, I think just permanently removing their ability to have any effect on the world we live in, by their speech, money, action, position, etc, as quickly as humanly possible is far more important than just carrying out old fashioned punishments for catharsis. We all just need them gone.
This happened to me before. They unbanned and rebanned me like twice, the IT guy emailing back was very sure I was using "scripts" of some kind that were harming the website, somehow. Ultimately I just stopped visiting KYM.
