Well of course. What I’d like to see are some stats. Are lefties 10 times more likely to use the F word in their internet writings or 100 times?
Well, just today I did a custom Google search of some websites, using f*ck, f*ucks, f*ucking, and f*ucked as keywords. Here are the results:
democraticunderground.com: 765,000 hits
dailykos.com: 136,000 hits
huffingtonpost.com: 38,000 hits
freerepublic.com: 20,600 hits
It isn't dispositive because some of the usages, especially on FR, are in context or quotations. Such is not the case on the other sites.
Just go to the DUmmies and see the profanity. And if they have an avatar of a rainbow flag, the profanity doubles and triples.
