@freejazz - I understand your point, but there is a similar counter example which I believe is powerful.
The gay community made large strides as a movement to allow a civil discourse and transparent conversations with others who opposed their lifestyles by deciding to be open rather than secret. When people meet face to face, and realize we're all really similar - people tend to soften their views to be "human".
Who is stopping them? Twitter? Twitter isn't the public square - it's just a website. It's full of advertising money that twitter controls and takes. It might be LIKE a public square, but it's not the public square.
