Ultimately, we’re discussing two different styles of communication that I don’t see as any better or worse than each other - everyone finds what works for them in their circumstances and environment and your style probably works great for yours!
There’s a fair bit of hostility and harassment I encounter in public for various reasons, and I also have some inherent difficulty processing speech and verbalizing. As a result, I take a pretty blunt approach to communication - one in which I do not mind showing that I’m angry, because that is a necessary thing to be sometimes.
I practice mindfulness a lot and do not generally feel required to say the first thing that comes to mind. But if a drunk asshole is following me home, I’m not looking to outwit em. I’m looking to stay focused on my safety while letting em know that I see em and I’m probably more trouble than they’re looking for.
In serious conversation with people I care about, I do swear, but it’s because phrases like “I’m so fucking sorry that happened to you” come naturally to me and are effective. The emphasis that a little bit of swearing can add in moments like that is pretty useful.
This all doesn’t have to be your thing, like I said this is all down to personal preference - but it would be a mistake to assume that people who swear aren’t communicating as meaningfully. It’s just another tool that we have at our disposal.
definitely helps to bow out instead of talking down to a beginner. “it seems you’re having an issue with X, I would recommend reading up on Y and Z because [how they relate to your problem]” is helpful, a very natural stopping point, is useful to people who search and find the thread in the future.
