Occasionally a relationship between fun and political orientation is pointed out; usually here, of course, the relationship is that Christian Conservatives are basically puritans, defined by that old aphorism that puritanism is the fear that someone, somewhere, is having fun. My experiences tended to differ from this (although not always), perhaps because of the liberals and conservatives I've run across; some musing inside.
For background, I've spent some time living in Texas and Georgia (both obviously quite conservative) and went to college at a consortium of liberal-arts colleges in California (rather more liberal, I should say).
My experiences from college, for whatever reason, usually gave me the impression that "liberal" student groups on campus were the ones engaged in a "war on fun", seemingly popping up to protest nearly anything they could find something protestable in, no matter how innocuous. One of the more memorable examples was a dorm that planned to have a gangsta-rap-themed party, entitled "pimps 'n' hos", which was simultaneously protested by African-American student groups and women's student groups. Another dorm ran into some flak from the same women's groups over its plans to include a female jello-wrestling competition as part of its festivities (despite the fact that the women planning to take part in the competition were among the people actually organizing the event).
To be fair, I imagine that various social-conservative groups on campus also had a dim view of these events, but I didn't hear anything from them, and they didn't make any sort of public noise about it. One hypothesis is that in the atmosphere of a liberal college campus in California, they're used to being outnumbered, so generally keep to themselves, whereas the liberal groups see themselves as having more power and numbers, and so are more likely to feel confident raising a ruckus.
In any case, the general tension throughout much of college was between libertarian-leaning conservatives who enjoyed antagonizing various "politically-correct" groups on the "left", and said groups successfully being antagonized. I can't remember any incidents of conservative groups really making any fuss, even when one of the colleges had a school-sponsored seminar on female masturbation (complete with demonstrations on dummies).
In Georgia and Texas, as you might expect, things are quite different. This leads to a hypothesis that those in the majority (i.e. those who are either in control or see themselves as in control) are generally the ones who attack things other people see as "fun" that they see as "immoral".
Another hypothesis is that liberals and conservatives are both largely split into two groups: Among conservatives, there's the social conservatives versus the "South Park conservatives"; and among liberals, there's the civil libertarians and hippies and laid-back anything-goes people versus the politically-correct pressure groups.
So are my experiences just odd?
