I think disappointment in people is a very reasonable attitude. In fact I think cynicism towards people in general is one of the core defining attitudes of our time, and it transcends political boundaries.
But as a filthy leftoid, I believe that there are socio-economic forces which are responsible for how people are in a given era. The spread of misinformation on the internet, social alienation, poor education with no media literacy, logic or critical thinking - these are not innate flaws in human kind, they are failures of society that can be fixed.
So you can see we have a real problem, because leftism and even liberalism is built upon respect for and faith in humanity - but very few act like it.
Well if it’s really absolute then you could legally point a knife at someone and say “give me your money” . You haven’t caused physical harm at that point and you’re only exercising your freedom of speech.
You could say OK, that’s not allowed because you’re mugging somebody and that’s a threat of violence. But in that case you’ve carved out an exception for threats of violence and therefore calling for violence against a person or group also becomes not allowed.
What about exceptions for fraud? What about for verbal abuse or harrassment?
And if you’re going to have exceptions, then how do you deal with obfuscated language and insinuation? “Would be a real shame if something bad were to happen to your family” - is that allowed? A nice friendly, supportive comment like that? If you can’t say that you can’t say anything.
Or that’s usually how it goes with people defending hate speech or veiled threats of racial violence.
