Well clearly you agree with me, not disagree, because you have a specific reason for why you think they shouldn’t be used.

Secondly, you’re misunderstanding what swear words are. It includes insults, but that isn’t what a swear word is. Swear words at least as often don’t even refer to people, as in “fuck! I stubbed my toe!” and “damn I’m late for work again”. And in fact very often they’re used as positive words, as in “shit i love that tv show!” and “that motherfucker really knows how to play the bass!”
