Hate speech existed before Twitter and will likely persist after it. Other social networks that allegedly do not practice content moderation also have identifiable hate speech content in them.
If you're going to reduce the argument solely to twitter, then can't you say the same for any other alleged "cause" on twitter being censored? And therefore take your argument up with the parent poster instead of me?
We are not discussing the right of a private company to refuse service. We are discussing Twitter's right to refuse service to the NY Post for posting misleading information with the goal of interfering in a presidential election.
And what causes it??
What if censorship itself causes hate speech?
