Maybe these nasty posters you refer to don't hit the abuse button and ping the Admin Mods when people respond to them in kind. JR has referred to it as having "unclean hands" and he doesn't put up with it for too long.
You seem to think as if it's all one-sided, but it's not.
I know one of them does, this particular person has a very quick trigger, and often pushes the abuse buttom, pings Moderator and so on. This is the same person who threatens to have posters killed. It's a little too much for me.
FL was a lamb by comparison, and FL meant well for all of us, I think he/she really believed the smallpox vaccine issue is a great threat and is worried over it. Of course I hope those of us who are worried are wrong. I hope Sabertooth and the rest are correct, because the whole issue is about staying alive and healthy. I think we all want what is best for our country and each other.
