I really need a gif of eyes rolling. Your statement is just flatly untrue, as proven by any Palin thread you care to open. I don't think I've seen a single one over the last two and a half years that didn't attract a swarm of ugly, negative commentary by Palin detractors.
With the recent speculation about her imminent entry into the presidential race, the volume and ferocity of irrational attacks against Palin on this site have gone through the roof.
Jim Robinson has the patience of a saint, in my opinion. It's no secret that he's a big Palin supporter, yet he has allowed not only fair commentary from those in disagreement with Palin, but also the sort of unhinged venom that is normally only uttered by leftist moonbats. If anything, I think he's bent over backward to maintain a hands off policy regarding the commentary here, only zotting the very worst offenders.
Don't support Palin? Feel free to say so. You're in no danger of being "purged", unless you insist on it.
