That's a wild assertion. Everything I've read suggests that stress- how people manage it, how effective coping is, what levels of stress are acceptable, what causes stress and to what degree- is highly specific. I don't think your generalization is true and I'd want strong evidence before accepting it.
It really isn't a wild thought.
For example, if someone was called a swearword but were oblivious to the meaning of the word, that person would be unable to be offended by it. Ergo, you cannot force someone to be offended, the words itself do not actually matter and have no power on their own.
Now, with a person who does know the meaning, the situation is a bit different, at least when that person suffers from the rather common misconception that words from someone else have power over them. But even then, they also are entirely capable to also know that they don't have to take that offense and don't let the word affect them.
Another person cannot force you to take it, though many are conditioned to take it instinctively.
Honestly, this entire thing is weird. For the ability to be offended by a word, one has to put in the effort to learn that word, the context behind it and all that. And what does that effort bring them? The ability to feel bad after seeing it written or spoken, hooray!
And no, that doesn't even only apply to cursewords in foreign languages: '
Troon' for example, it only is a bad word because of people knowing the context behind it, but what if someone who is transgender and really doesn't pay attention to the entire culture war garbage, because they never used mainstream sites or something, witnesses it for the first time, without any context? Would they be able to tell it's a swearword towards them or would they read it as something toon related perhaps?
Point is, no matter the persons stress tolerance, the entire fault is the misconception that words can have power over your mental state, it's a dumb system made up of arbitrary rules that change every month or so that honestly stinks.
What one should pay attention to is the context of what the speaker/writer is intending to transfer: Is it a simple shitpost or does that person intend to raise hate against a group he is talking about by misusing rhetoric? That is the important part.
