So now everybody has to change speech for a very very small minority?

Yes, if you lean politically hard left in the USA. This has already become a political talking point for transgender people, and all censorship is good censorship under those claims.

No, if you're simply liberal or conservative in the USA. They generally think that speech should be uncensored until it's directly causing legitimate violence (e.g., yelling "fire" in a crowded theater or threatening death).

Speech? No, that's free. We're talking about hurting people by not getting vaccinated.

YouTube is a private company. Them censoring someone is not an infringement on free speech.

You’re hiding behind legality. The spirit of free speech is most definitely damaged.
