I kind of think in terms of hockey on this. It is usually the one retaliating that gets the penalty. Not right, but common.
THere are at least a few here that goad people until they lose it and then act all innocent when the responder goes off. I think they should suffer a penalty too, but apparently do not. FF, even though you are usually a retaliator, you start some too. I have seen topics going along sort of okay, and you make a "stupid Repuke" or similar and get the other side going. But, I will agree that they do go after you awfully hard and you usually retaliate. It seems unfair that one can't "get even" but that is MT's rule.
Personally, I wish they would crack down on doing copy pastes without credit or links as their own. And another biggie is false information. I know it is difficult to say that this is all true or not, but here seems to be a great deal of mostly very false crap tossed in with some fact lately. Usually a supposed repost of an email. Like that is supposed to be a good source.
