Does it seem to you that a certain 4 letter expletive that starts with F and ends with K is a lot less shocking than it used to be? Perhaps it is, as discussed in this article in the Guardian. (Lots of foul language in the article. DUH. Must have been a fun article to write.) Of course, this article is from the British perspective, and they probably are less conservative about this in general than Americans. Still, though, I think it is true that we are much less shocked by that kind of language than we were even 20 years ago.
