I really enjoyed your take on cursing: I think cursing, like everything, has its place and time. I have worked with people who cursed all the time and, although I am not a puritan, it did get to my nerves after a while.
Incidentally, your last sentence:
"don't use dang, or shucks, or monkeytrucker, or the like… it's really gay. Curse and be proud..."
may offend more susceptible readers with a different sexual orientation.
