In only the most playful and harmless spirit of sarcasm, it kinda reads like, “you are immortal if you make choices which do not kill you”.
And as an extension, “if you choose to survive long enough, that will eventually kill you, as well”.
It sounds like a complicated way of describing an instinctively non-suicidal existence.
While the communities you view may differ from my own experience, I would say that political and news themed communities have had an uptick in aggression.
My sense is that it is less about the overall population on Lemmy, but more about the polarization of news and political topics in our society. If there were truly a force actively trying to promote a culture war to prevent a class war, I’d say they are doing an effective job.
Outside of news/politics communities, postings, and (directly or indirectly) related comments (or commenters), I have not experienced an increase in outright negativity and rudeness.
Just like in any written dialogue, I think some expressions of humor can be written or received poorly, lending to a received sense of rudeness—and those moments sometimes serve as reinforcement of actual offensive aggression observed elsewhere, you dick /s.
Jokes aside, I do appreciate you drawing attention to it, as a reminder for each of us to do our part to express ourselves more clearly—allowing for discussion, disagreement, sarcasm, and humor while maintaining respect and civility.
And, of course, continue to block users and communities you find objectionable; though, I would challenge anyone to ask themselves if they are blocking to avoid offensive content, or are they blocking to avoid content which does not align with their views. Silencing different points of view, ultimately, only expedites the original problem.
