I see it completely differently -- I see one political philosophy where that underlies basically all of it, and another that's vehemently against that. And so I see it as independent of fanaticism. For example, I'm a far-Right guy, a "fanatic" if you will, but I don't believe in doing any of that. In general I reject the "both sides are basically the same" simplisticism, in most of its popular applications, as naive and insufficiently studied.
This is really the part that bothers me about your entire post--when I've got my dad saying that any news source that isn't Fox News is lying and unpatriotic, I've got presidents of both parties using "Free Speech Zones", I watch the cops shut down demonstrators and performers alike at both conventions every time, etc. I really can't see any institutional difference between the Democrats and Republicans in this regard.
It's certainly possible to be a far-Right guy and NOT be a fanatic--I don't reject the political positions of the far Right as wrong on their face, after all, I'm a pretty adamant balanced-budget and strong-military kinda guy.
Really, I think when you can't acknowledge there are complete jerks on all sides of the political spectrum, THAT gets dangerous. From my point of view, I feel like you're putting on the blinders a bit and ignoring the people who are calling for this kind of stuff while they're on your side. Speaking as a guy who votes split ticket all the time, and who votes in every election, I just can't see that neo-Liberalism and neo-Conservatism are any different--both of 'em want to take away more of my freedoms than I'm comfortable with, both have a habit of trying to suppress debate, etc.
If this isn't happening where you are, you're arguably lucky, but here in State College, it seems like there are more disruptors than there are debaters on all sides.
Oh, and as for "how it should be" with regard to the university's influence on this area, that kind of stuff only goes so far with me when it's people outside of my district trying to media-saturate my district--this is probably, for example, the number one reason why I'm going to not vote R for Senate next time it comes around, because Twoomey is 100% grade-A jerk and it comes across in everything he says (aside from being an anti-liberty force of the Christian Fundie type--again, I know a lot of Christian Fundies who are great people and NOT interested in taking my rights away. He's not one of them.)
It's entirely possible that I'm biased because I'm in an area that's a focused target of the worst the Republican and Libertarian parties have to offer--the former because it's a blue county in a swing state, and the latter because it's a college town and therefore their most fertile recruiting ground. On the other hand, I see these efforts as just as potentially frightening as anything on the national stage, especially if a lot of us here, including me, get our way with regard to the relatively higher importance of state and local governance.
