I couldn't give less of a fuck about cursing being bad. If I wanna fuckin' curse, I'm gonna fuckin' curse, and nobody but the Mods can do shit about it! (Mods, please don't kill me)
All that swearing says about me is that I'm fine with using it. Does it give people a negative view on me? Of course, but that's only because of the loose stigma surrounding it. Cursing is far from a serious matter. In fact, I'd say it's one of the most widely-known mundane ones. Little kids curse because it's something they're constantly told not to do, thus they do it out of some silly rebellious attitude. Older kids curse constantly, and "fuck," or any other curse word, is a standard part of the average US adult's daily vocabulary.
Despite that, we still demonize cursing, and I believe it's because demonizing said words have been ingrained in our brains since childhood. When I meet someone that freely curses, my respect for them drops slightly. This makes me a huge hypocrite, since I curse like a sailor, but the difference between me and them is that I do it in private, or in situations where cursing could be considered appropriate (ie getting in a car crash with my new car).
From what I've read, the only cursing-related thing the Bible talks about is using the Lord's name in vain. There's nothing about "shitheads" and "assholes," so that doesn't explain why we stigmatize cursing like we do. I don't know, man. History's weird.
