A better question is where is the line between ‘simply’ a controversial opinion and actual hate speech?
Because if a platform is required by law to ban hate speech, that’s going to sweep up a lot of controversial opinions along with it.

Is it ‘hate speech’ to express any negative opinion about an oppressed group? And if not, where do you draw THAT line?

(if you want an answer to your original question I wrote one out but it’s somewhat long…)
