Some, if not most, posters on DailyKos exhibit the characteristics that I deplore in conservatives. Look, everyone is an American. We have different viewpoints and our individual viewpoints are legitmate.
The ideal liberal attitude, in my view, is that every American should get to think and behave in the way they choose. People who want to get an abortion can get one and those who don't want to get one shouldn't be forced to do so.
(Up to the point where we bump up against what other people choose to do, and there's the rub.
We have a lot of people in this country who are conservative and liberals should support their ability to behave as conservatives (up to the rubbing point). We shouldn't treat conservatives as second class citizens, or call them dumb or mean. (Let them do that to us if that's what turns them on).
The same goes for blue dogs. They are Americans. Liberals should acknowedge their existence: they are here. We should acknowedge the validity of their viewpoints, the same as we acknowledge our own.
Liberalism should be about a ground up society. Conservatism is about authoritarianism. Bashing blue dogs is authoritarian. (And by my own logic, I suppose, liberals should be able to choose to be authoritarian if they so choose).
