How can people fall for this trap of discussing Parler incident as a transgression of free speech? It was a vile specialized platform that fostered very particular anti-social, frequently murderous behavior. They had plenty of time to prove otherwise and they clearly did not care or did not want to.
Now they poison the actually good idea of free speech with their infantile appeal. In theory and in practice they are on the wrong side of history and everyone involved is less and less redeemable as they try to flip the situation and present themselves as victims of oppression.
Sure bad apples / users exist but calls for violence on Parler were systemic and we have proof now.
