I think that we are fighting selective perception on the part of the Conservatives. In the majority of threads where someone is coming in to bash Bush just for the sake of bashing Bush, my experience is that the poster tends to be admonished by one of his own for doing so. The thing is, though, what the Conservative posters seem to take away from the thread is that there was some ill informed, emotional boob. Not that people were chiding that person (for example, I don’t "sprinkle my posts with “I hate Bush” as Friend Shodan states is required, yet somehow don’t get piled on (I have been scolded a time or two for being an asshole, but that is a different matter and probably well earned). If I may be permitted a small dig here, I would guess that the posters (like Shodan) get a pile on for reasons divorced from their personal politics and more related to their personalities. Just my opinion.
The other thing to keep in mind is that at this moment in our history, we Lefties are feeling very under attack in every aspect of our waking lives. The things that we believe and the things that we hold dear are being assaulted and eroded. Not only that, but the strange part is that this seems to not be enough for the opposition. It seems not enough that they are controlling everything, but they seem to have this strange need to grind our faces in it. Given that, I guess that we would ask for your patience.
Finally, it can become hard to always police our own. Think about it this way: If in the threads where one of our own is being unreasonable where we do speak out the message that our Loyal Opposition takes from that is just the loon and not the fact that the loon was called on his behavior, there is really no incentive to correct that person. Couple that with a desire to have a somewhat united front, and there you go
