I love South Park its actually in its plotlines and message of each episode one of the most politically conservative shows on TV( I don't believe people who watch it will swear less though I certainly swear a lot less than I did in High School before it came on).
The creators are Libertarians, and open admit to voting Republican. So, yeah, I would say it was conservative.
But sitting little Johnny down to watch Butters deal with having testicles for a chin..... I dunno.........
