A majority of developed democracies have laws that restrict hate speech, including Australia, Canada, Denmark, France, Germany, India, South Africa, Sweden, New Zealand, and the United Kingdom.
That said, I disagree with what eBay is doing.
This won't end well.
As a separate point, Canada's hate speech laws have been working quite well. They're used rarely, and only in extreme cases, like a case where a promoter of the Rwandan genocide wanted to immigrate to Canada. Judges understand that "speech I hate" isn't the legal standard for hate speech.
They do for now. But if you'd been paying attention lately, you'd know that the dominant ideology among our elite universities and a growing number of our institutions is no longer liberalism, under which free speech is valued. Liberalism has been replaced in the univeristy by critical theory, and its offshoots like critical race theory, under which it is absolutely 100% taught that hate speech is precisely equivalent to "speech I hate", or more accurately, speech the left hates. Argue back and you'll probably get sent that meme about Popper's paradox of tolerance, but it's actually based in the Marxist philosopher Herbert Marcuse's theory of "repressive tolerance", which basically states that far-left radicalism should be tolerated and nothing else.
Critical race theory (which could best be summarised as "anti-scholarship racism masquerading as anti-racist scholarship") was born in law schools and is now being taught as unquestioned fact throughout the education system, to children at an increasingly young age (which is the whole point of cancelling Dr. Seuss - so they can shoehorn in pro-CRT books to children instead.) Lest you think I'm being paranoid, here's none other than the American Bar Assocation propping up CRT: https://www.americanbar.org/groups/crsj/publications/human_r...
Where do you think the next generation of judges is going to come from? Don't say you weren't warned.
