Just how free should we be to express our opinions - however hateful or harmful?
Germany, for example, has a controversial new law that tries to control online hate speech: Free speech vs. censorship in Germany that many think goes too far. Hate speech is free speech
What I have found interesting though is that even in the US with its First Amendment, speech isn't as free as you might think: What Type of Speech Is Not Protected by the First Amendment?
The list of limitations is long including libel, slander, obscenity, pornography, sedition, incitement, fighting words, classified information, copyright violation, trade secrets, non-disclosure agreements, public security, and perjury.
Like most things in life there are few absolutes Things are nuanced including freedom of speech.
Lest we go to far in limiting freedom of speech keep in mind Prof. Jordan Peterson's passionate defence of free speech.
