I am weary of trying to explain to people that withdrawing a platform from people pushing hate-speech is NOT withdrawing their freedom of speech. So here's a decent piece in the Guardian that makes the point - here's an extract: "Most freedom of speech debates now start on the false premise that denying someone a platform is censorship. So we must begin with the correct one, which is that freedom of speech is freedom from punishment. If you are not being convicted and penalised by the state for speaking, then you have freedom of speech. If just one channel of speech has been denied to you, you still have freedom of speech."
