What happens if you don't use the correct pronouns someone has declared for themselves?
Is this not "imposing beliefs" on other people?
This goes far beyond "tolerance": you must be an active, enthusiastic participant or face punishment.
> It's very easy to hide your beliefs if you want to participate
That's the point: only one set of ideas are allowed, everyone else must hide, regardless of forum.
> anyone is free to join and start getting support
Try espousing ideals contrary to theirs in completely unrelated venues and see how much support you get sans anonymity.
> places that don't make people feel unsafe.
"Feeling unsafe" is an outstanding weapon to crush behavior one doesn't like. Doesn't even require logic: it's literally a feeling.
