Jesus! One would hope the “I hope you die” thing involves a large degree of hyperbole. I’m sorry if I gave the impression that I think Rush (or anyone) actually hopes all liberals die. But I guess we’ll just have to disagree that there’s a difference between:
“You’re a horrible person whose ideas have no merit.”
and
“You should be shot before those ideas are allowed to spread further.”
The first is absolutely a personal attack (as is the second, obviously), but I personally think it’s easier to discount the speaker in the first than the second. Maybe it’s my squeamish liberal sensibilities (heh… referring to myself around here as a liberal amuses me!), but I think there are orders of magnitude difference in the contempt of the two.
To your point, though, I absolutely agree that both sides partake of plenty of personal demonization because they feel that someone having a contrary idea means they’re stupid, wrong, whatever instead of what it truly means: That they have differing ideas. There are times when I can’t even begin to fathom how someone could see certain things so differently, but I almost always try to ascribe it to worldview differences rather than personal malice, incompetence, etc. And our political discourse (and country as a whole) would certainly be better off if all people did that.
Nevertheless, in terms of dragging down discourse I think folks like Coulter and her continual calling out of the president as a retard, or Limbaugh’s completely over the top attacks do have an affect, and inasmuch as the conservative side seems to be more over the top than the liberal side (at least in terms of noteworthy national figures) share a bit more of the blame.
(I actually have, in the past, admired some GOP politicians despite my democratic leaning. If it was Huntsman Jr. instead of Mitt, I think I’d have a much tougher time, particularly if the rest of the GOP looked like him instead of the tea party-esque composition we currently have. Likewise, before 2008 and his hard right keel to the party line, I had fucktons of respect for McCain’s ability to look at things rationally and act accordingly.)
Ultimately, I think the current political clime is far more detrimental to the right than it is to the left. The conservative identity crisis currently playing out seems custom-designed to enfranchise the fringe at the expense of the middle, but history generally shows a constant liberal skew as generation after generation is born simply through the march of societal changes. At some point it seems like running away from demographics is going to bite the GOP in the ass.
