As an American who isn't offended in the slightest by swearing, all of this Brit condescension is much more offensive. We get it. You like to think you're so much more sophisticated. Even a slack-jawed blog proves this.
You have to admit that in general Brits are much better than Americans at swearing though. The problem in this case is simply the stylistic choice to rely primarily on "fucking" instead of the usual variety of flowery vituperation.
I'm not sure any of us Brits think our ability to swear is "sophisticated".
It is possible the posting could have been made with humorous intent.
