considering some of the attitudes in America these days, it's quite likely that he's entirely serious.
I think you would be walking around a long time before you met an American with such views as his.
And I don't mean websites. You can find wierd ass people all over the internet. Advertising German cannibles, Spanish imams instructing people on the "correct" way to abuse wives, etc.
I think you would find American life far different from what is protrayed on BBC (and other media, for that matter).
Having said that, it indeed is an offensive website, whether or not he was joking.
