> Using profanity indicates a weak vocabulary. A lack of discipline. A degree of unrefinement unbecoming

Says you. I think not swearing obviously indicates a weaker vocabulary since there's a lot of things you can't or won't say.

Of course, swear words can be offensive if you're their target, and I don't really enjoy that side. But they are _very_ effective in communicating frustration, anger, surprise. I think using them brings a bit of spice to life and a well placed "Fuck!" can feel extremely cathartic and... dare I say... pleasant.
