Heh, the thing is, if in the UK, someone made a joke about Public Schoolboys and Homosexuality, for example, it'd all be taken in good humour, I mean the whole thing is such a gold mine for comedy (for example, seniors in the highest class schools are assigned Freshmen to teach them the ropes, these Freshmen are called 'fags'.. this is true.) it doesn't really state an opinion on the concept of homosexuality, it simply states that (until recently) an all-male environment where older students are assigned fags is a breeding ground for comedic imagery.
There's a reason that 'Hello Sailor' was a catchphrase for homosexuality for a long time, because it was similar all-male environment, all alone at sea for long periods of time, the Navy was victim of joke after joke about it. In many ways, it's kind of an indictator of how times have changed that now people are worrying about the exact opposite...
