My comment has nothing to do with whether Youtube should have the power to do what they've done. It has to do with the assertion in the GP that it's not misinformation to say unequivocally that cloth masks don't work. That appears to be nonsense since there's a handful of studies that at the very least leave open that question.

Have a look at Fig 3.A from this study:

Therefore they should lose sec 230 protections.

Losing sec 230 protections would mean more ban-hammer for lying politicians (about elections, vaccines etc.)

I'm fine with that. It would create an even playing field in theory and that's a hell of a lot better than what we have right now which is some politicans getting to lie with impunity and others having their content removed for wrongthink.

Hate speech is not "wrongthink".

Don't defend racists by pretending they are just thinking outside the box.

There in-lies the problem. "Hate speech" is just speech you don't like or choose to be offended by. You have no problem with "hate speech" that suits you and your political worldview.

Don't defend the current situation by pretending that it's only hate speech and racism that are getting removed.
