Well, we don't really have skinheads or communists around here (the latter is more of a King's college thing). We do have plenty of gay people though, as is somewhat traditional- and yes, some excellent satirical comedy too; http://www.srcf.ucam.org/pet-jcr/thesex/mich04.php . You might find it slightly in-jokey for your taste though.
Scene must have changed over the years. I decked a skinhead with a solid right hook - one who was assaulting some tourists. In Cambridge. Pretty funny, the look on his face, that is.
As for a satirical comedy targeting the bugger/secret society element in the International Communist Conspiracy. It could combine Kubrickian irony with the farcical zest of Monty Python. The Grail Knights arrive at Castle Anthrax but instead of finding the submissive grail maidens, they stumble upon a hideous ritual initiating members of The Apostles into the KGB. Diapers would work well for Commie buggers toting Kalashnikovs and singing like cherubs from King's.
