There's nothing wrong with swearing in my eyes. What harm is a word? Then again, I completely against racial slurs? Whats up with that?
Depends on how much you swear, if you go on some prolonged rant then yeah it can make you look pretty awful.
My favorite government grant story was during the Clinton years. He gave a $2,000,000 grant to a friend to make a video to aid homeless people find clean food in places like garbage cans... The only problem is that most homeless people didn't carry around with them VCR's & TV's to watch the video with.
