I think this is subjective.
Swearing in the workplace is much more normal here in Australia. In my first job at an American company, I was shocked how prissy people were about swearing. In my head I thought “these are adults, right? Why is everyone acting like a blushing teenager?”. I’m sure I sounded rough as guts to them. It took ages to learn to scale it back depending on who I was talking to.
Swearing with someone about / at work is kinda an Australian way to say “I trust you and feel relaxed around you”. Forcing myself to not swear felt at first like I was pretending I didn’t like my coworkers. It was weird.
> where we practice swearing Oh well hang on a second…that could be fun
I should also mention that this attitude is not just a liberal vs conservative thing. I've lived in Austin and Houston and Dallas (all three are about as liberal as any other major city in the country) and swearing in a formal setting is frowned upon in all three.
A few years ago, they went to a fan event here in Japan hoping to buy multiple copies of a zine for their friends overseas, and when told they could only buy one copy, they stood in front of the stall and cursed profusely in English out of frustration. After the event, they found that the Japanese side of the fanbase had unfriended them and removed them from online communities because of their outburst. They were completely blindsided by this. (In fact, their version of the story was just, "I went to an event in person and after that everyone unfriended me, I don't know why they're like this." I only heard about the swearing incident from a mutual friend.)
Anyway, there's obviously degrees and nuance here but I think people who swear profusely-but-not-at-anyone-specifically don't realize it still sometimes comes across as hostile.
I don't think swearing is necessarily negative though; it can often be fairly neutral, or funny/positive. But again: in text it can be tricky.
I see three reasons to use swearwords sparingly, even though they don’t particularly offend me.
1 Managing my own emotions. Most swearing is negative and that drags you down which is not very productive or fun.
2 Managing others‘ emotions as they burst out, which stresses the people around the swearer.
3 Some people just can’t say a fucking sentence without gratuitous swearing which makes them sound fucking stupid.
