Nope, I’m thinking Twitter should either be a publisher or a moderator, one or the other. If they want to be a publisher, then they must allow all opinions but take not responsibility for them. If they want to be a moderator they can take a side but are responsible for it.
You are claiming that they have two choices, express their own viewpoint or not express their own viewpoint. And you want the latter choice to trigger a government punishment in the form of civil liability. Civil liability for expressing a viewpoint in their media product. 1/2
