It’s human nature to provoke especially if it has no consequences. On X being a provocateur comes with financial reward. So of course civility breaks down and discourse becomes increasingly toxic because you make money with little to no social consequences.
You can either have constructive, civil discourse with context of identity, be rewarded for putting your neck on the line or preserve your privacy & anonymity, continue to be a provocateur but with nothing to gain from it.
You just have to stop incentivizing anonymous posting with $$$.
