I don’t twit so I don’t have a dog in this hunt. But I never understood how they could justify censorship. After all you are on Twatter voluntarily, and you choose what to look at or not look at. It’s not like groomer teachers that have a captive, dependent audience.
It's simple for them. They define 'hate speech'. Anything they don't want people to say is 'hate speech'. Saying, 'a transgender woman is not a woman' is hate speech as they define hate speech. That's how they justify it.

Yes, they could not read your tweet but it's more than that. Just knowing someone on twitter doesn't agree with them sends them into a manic rage. That's how unstable they are.
