Expressing certain thoughts is already dangerous in some contexts. Not state-actor-is-coming-to-get-you levels of danger just yet, at least for us common folks, but it's already happening and it ain't gonna get better.
It certainly is, but anonymity and pseudonymity tend to protect you unless you get some sort of celebrity or need to communicate for your job.
Anyway, one expresses one's opinion for the sake of other people. Maybe instead of worrying about what other people think, I should concentrate on my own safety. I can do other things for people.
