The left thinks they can have it both ways... ideological-unity and tactical-unity (unity against specific threats).
The fact that 'they' cheated in 2020 is only delaying the inevitable crumble-ization of their naked powerplay. Because capitalist 'group individualism' will adopt anarchistic countermeasures to fight back... Free discussion of ideas over cancelled conversation. If you're not free to speak-out against your ideology, you see what's happening on the left right now, as a result. Chaos.
