Replace hate speech with advertising and it reads the same.
Notice the ones defending crazy "free" speech are the same who defend crazy capitalism? Yeah, that's the issue: by defending what I call "responsible speech", which is free but not ultimate, we are defending social welfare and human rights AGAINST the former, because the former has no interest in defending the latter. We see it even here in Hacker News, when a corporation does something unethical or morally wrong, there will be someone to say "but hey, the corps are right they exist just give shareholder profit and that's what they're doing". It's a serious debate about sustainable development, which has the very survival of our species at stake.
