[No, we got away from the practices I mentioned above through discussion that did not take place in a "public" town square. Basically anywhere else, but certainly not the "public" town square. One reason, among many, is that a "town square" is not nearly as ubiquitous as you seem to believe, historically. Dominant ideas can easily and are frequently challenged on Twitter and in modern discourse generally, it's just not tolerant of the racist, awful ideas that some might want to discuss. It's not going to lead to progress to continue to discuss how one race is superior to another, for example, and yet that's all some groups seem to want to talk about.]
There's also a cultural aspect that can't really be solved by Twitter, like petitioning someone to be fired for making a gay joke ten years ago.

So are we gonna be biased or call every guilty party out?
Or was your statement made such that only the right wing makes such headlines?
Or are you russian and just trying to sow division?
Which is it?
Also you still didn’t change what I said, just avoided it by trying to claim “whataboutism”. Fight it all you want, it’s not going to change the truth.
[Free speech and the open town square is how we got away from the atrocities you outline. There is no societal progress without free speech, which twitter is actively clamping down on. It's regressive and taking us back to when dominant ideas couldn't be challenged.]
