To illustrate: absolutely free speech would imply the right to harmfully agitate kids for whatever your cause is. Does it seem obvious that this is a bad idea? Then just extrapolate "kids are easy to manipulate" to "adults are mostly just older kids".
And btw, I know what it's like to be on the other side. That doesn't justify turning a blind eye to the madness that comes with absolute free speech.
Either you accept that a line has to be drawn somewhere, or you accept every consequence of absolute free speech. Which, imo, would be a terrible idea with 7 billion people just waiting to be gamed through their fears.
Don't get me wrong, I don't consider what we're seeing here unproblematic at all. I just don't consider absolute free speech to be unproblematic either, quite the opposite.
