I disagree entirely with this article.
He doesn't define hate speech. "There is no place in this world for blatantly false allegations or denying historical evidence", what does it have to do with hate speech?
Also saying that freedom of speech "is about being able to speak out against your governments without fear of oppression." is a very limited and US centric viewpoint.
It's funny how people don't see the danger of supporting these soft-censorship feel-good policy while more and more authoritarian politicians get elected, surely these laws won't backfired?
And that quote of Voltaire is apocryphal (but he said something close).
