I suppose the silver lining is that swearing retains its potency as long as people find it offensive. In a sociopolitical sense, the n-word (evidence in itself right there) is the only one with any real weight attached to it any more.
As a Brit who swears constantly, uses a lot of slang, and enjoys drowning every sentence with relatively acerbic sarcasm I'm curious how I'd fit in polite American society.
