Freedom of speech is an essential human right, to criticize and although that right may offend some people, no one really has the right NOT to be offended. Yet our human rights are continuing to be eroded, by well-meaning but deeply flawed legislation in the west, by western courts of law, by growing censorship from social media, by "wokespeech" etc.
