Oh it seems to have worked wonderfully thus far but I see this as a sign, in tandem, with the rising tensions of today's youth, growth of the internet and fascism. I am totally for some levels of control but honestly I don't like what I'm seeing in that tweet because the entire "hate speech" debate seems very disingenuous to me. There's so many Youtube activists who coin the term wrongly to slander whoever isn't with them. There's a lot of "fake" accusations of "hate speech" being thrown around these days I think. There's also a lot debatable stuff like Sargon of Akkad, which can seem a bit like covert hatespeech (I'm thinking of the "garbage human being" incident), you know, the kinds of people who dedicate entire video channels to cross-examining and dissecting what other people have said as they cherry pick everything apart to go "this must mean this person said this, ergo they're evil" etc.
I completely understand, what I will say though is that the law right now in the UK isn't that lenient when it comes to hate speech which is a good things as I'd rather not see criticism of people and beliefs become a thing of the past.
Such as the aforementioned Sargon who, while a disagree with a lot of his views, I feel that his opinions are important to society and advancing discussion on many important topics.
However, showing hatred for people for no other reason than to cause discord is, in my opinion, completely wrong and should not be tolerated in a egalitarian society where all people should be treated equally. (Of course, I understand the natural differences between people)
