All the others are not actual problems.
Actually, all of them except prudishness are at least minor problems, and even prudishness can be a problem depending on the situation, but none of them are really as bad as all that among forum Democrats (relative to other groups of people or other groups of Democrats) other than the tendency to take right-wing positions on economic issues.
I guess it depends how you define "problem". While all the traits cited by TNF are annoying to some extent, they are merely personal characteristics and are not actually issues affecting the course of policy (except possibly dislike for southerners, if taken to really extreme levels). I'd rather have all democrats be oversensitive, snobbish, slacktivist prudes, than have a single one of them be economically right-wing.
