It's amazing how much easier it is sometimes not to respond to a person with words, but just to "bark" at them. Solves all problems. In the first case, your attempts to smooth over sharp edges will be perceived as weakness, and weakness, as with any animal (and any man is not far from the apes), is a reason to attack you. Not to mention that polite communication itself can be interpreted as arrogance or even as a foreign language. Obscene language, on the other hand, sometimes accompanied by gestures and shouting, can paradoxically, equalize, bring people closer together, and help build the trust necessary to achieve the desired results.
The discovery is simple, I realized it a long time ago, but I never learned how to use it. The main difficulty is to know how to switch between "languages" quickly. Ideally, it should be lightning fast, but swearing exhausts me emotionally, while politeness makes me let down my guard.
Another great option is to say nothing at all. The older I get, the more I realize how that works. It requires a beer or wine and maybe some weed. The result will be shitty, but who cares? The key is to not create conflict or problems, and if you do, it's not your problems or your conflicts.
