When you think about the town square, anyone could set up a soap box, say anything and be heard by anyone... anyone within a 50m radius depending on background noise. Standing in the town square didn't give you the ability (or right) to be heard by anyone in any town square.
But nowdays, you can (and sometimes are obligated to) have an opinion on anything. Local politics in a country on the otherside of the planet - go right ahead. Opinions on the mid-east that most people are not qualified to provide, sure thing!
And worse, if the echo chamber deems that "silence is violence" not only can you not refrain from expressing your opinion, silence means you have out-group-think, so either agree or be removed.
Twitter was fun... for a bit. But its quite obvious that this idea that anyone can have an idea, and everyone can hear it is just plain bad for society.
In most of the world you have free speech - go outside and use it. But online for the world to hear... maybe thats just overrated.
