> but the reality is that you just can't show any kind of personality, humor, or fun on the internet without putting yourself at risk.

Completely untrue. Lefty "SJW" Twitter is full of humour and personality. Shitposting takes precedence over serious discussion, massively, to the point where more centrist or right-wing twitter circles seem completely dry in comparison. If your humour and personality aren't accepted, that's on you.
