Seeing as the tech companies have no interest in censoring based on "viewpoint" I don't see what difference this makes. Their entire existence relies on being the single point where everyone goes.
No Republicans have ever been removed solely for being Republican. People are removed for promoting violence and harassing other users.
The fact that Republicans consider violence to be a "viewpoint", and their viewpoint rather than that of a few extremists who use their name -- that worries me. A lot.
