I would like to be able to talk about politics with rational people ...[but]...the problem is that crazy views get too much credence here, due to an unwillingness to criticize by more rational people.

Right. It's those damn greens. Damn those greens, with their votes for... crazy green things! Not like us blues, who want nothing but good and rational blueness!

[ETA] My mind has been killed. This is why I don't want party politics -- as opposed to policy -- on LessWrong.
