This is not to say that all conservatives are guilty of group-think or that liberals are immune to group-think. In fact, I found myself a bit frustrated at some liberal group-think this weekend. But in my day to day life, I encounter moderate liberals, and I have chances to reason with them I have the experience of being able to talk them into avoiding some of the less rational position attributed to liberals. I have few such experiences trying to reason with conservatives. I'm sure part of the problem is that the conservatives I know are not moderate conservatives. But still, the point is that I have few positive experiences reasoning with with conservatives about politics, and when it comes to writing arguments, I draw heavily on my experiences with my target audiences.
I think that, ultimately, we liberals have to find ways to reach out to moderate conservatives; But, for the moment, I don't know how. In any case, this is what I've been stewing on. This is why I haven't posted much. My mind has some tendency to lock onto an issue, until I sort it out. This issue has been hard to get past.
