Unfortunately, the so-called "liberal side" is going for all the tools like censorship and banning, state interference in the corporate sector, and more that it berates the other side about, so there is no moral case here, just pure tribalism. Actually the "liberal side" invented all these tools but has had a vastly better propaganda machine and hides under the cover of due process and procedural justice that never seem to deliver actual justice to the people most in need of it. I'm glad the world is getting to see the naked body of the "liberal side" under Trump.
Regardless (I both agree partially yet think you’re omitting major differences here), you still live somewhere. When states are adversaries, that means there are consequences to being involved with the other state.
