However, excessive swearing does signify a disregard for social etiquette and an inability to comport one's self.
Whose social etiquette? Yours? Mine? Who gets to decide what is or is not impolite with regards to language? Who gets to decide which words go in the "naughty basket" and which words don't? Perhaps a relaxed attitude towards swear words is a natural evolution of culture and etiquette.
To assert that one is a condescending jerk for not swearing is preposterous; that's like criticising somebody for not speeding or not assaulting someone.
But that's not what I said. Or at least not what I meant. I don't care if people do or don't swear; whichever words you choose to use is entirely up to you. I take issue with people judging someone else's intelligence, self- control, or decency by language they choose to use. Perhaps I should have said "If you think by opposing swearing you are intellectually &/or morally superior to others, you're not." Or "If you judge another person based on how often they swear, you're a condescending jerk".
I thought what I said was pretty clear in the first place, though.
