This post, from the "TV Watch" segment of MediaPost, brings up the idea of what is considered "acceptable" language on television versus what is acceptable on the internet.
Nowadays we are certainly much less conservative about profane words in the media than in days of yore. This is partially due to the internet, where there is no filter that one must pass in order to publish one's information. If I wanted to, I could unleash the longest string of profanities the world has ever seen right here in this blog, and there is little that could prevent me from doing so. So long as one is not inciting violence or hateful acts against a group or distributing illegal material, the only thing holding a person back is his or her own taste.
I suppose this is a good thing. There are plenty of things in the world more dangerous than a foul mouth, and although it may be unpleasant to listen to, one can always click away from the page, or (as this article discusses) change the TV channel.
