Okay, if you don't like it when people swear, fine, whatever. It's your choice.
But when you start judging people as being offensive and whatnot, then why shouldn't I judge you as, hiding behind a veneer of sophisticated calmness and culture with a hint of politeness, simply being butthurt when your tender ears get violated? They're words. They can be used for emphasis as well.
And it's hardly a sign of 'mental laziness' if I swear when angry or something. They're, again, only words. That people use.
