It's not that I don't hate the people who cuss, it is just the words and/or usage behind the language. I once wrote an essay on the over-usage of curse words in todays society. It turned out good.
I feel that cussing is a sin to the tonge. Cussing itself is immature and degrading. It is much more sofisticated to describe your feelings with intelligent words.
My parents won't let me cuss, except they let me say "crap" if I use it correctly.
I hate cussing because it gives a sharp, nasty flavor to a person's speech. And no one likes that kind of speech
EDIT: Oh yeah, and I joined "The cuss LOVERS club" because I made up my own cuss words. "Sharpcheddar" replaces "Shit", "Fracktail" replaces "Fuck", "Arghs" instead of "Ass", and so on.
I hate cussing mainly cause I think you find better words to use instead. People tend to use cuss words in the most unnecessary places and they're sentences make no sense. Sometimes people add cuss words just to have them in there and it doesn't fit or sound like proper speech.
I hate it when people overuse it, and when people don't know when to use it. Unfortunately that happens all the time.
