There are like 5 people who post 90% of the content on lemmy. Cm0002 is one of them and really hates tankies / anyone to the left of them.
Most of the content on the “tankie triad” is general left wing anti-us stuff. Occasionally they’ll be some post praising China then some liberal will comment something about tianemen square or uyghurs, get banned , and then complain that the whole instance is full of genocide apologists.
It’s not like there are regular posts praising Kim jung un or maduro like the liberals make it out to be. There are a decent amount shitting on liberals, like the reverse of this post, which perpetuates this dumb instance war. It’d be best if it stopped as were all “radical leftists” in The eyes of the rest of society and were gonna need some sort of solidarity to accomplish the 90% of things we agree on.
America doesn’t work like that. Due to the way the electoral system is set up only two parties can be viable at any given time. The only time you can create a new party is in a realignment, eg. When Lincoln formed the republican party as an explicitly anti slavery northern party and the democrats became the pro slavery southern party. Prior to that it was the whigs and the democrats, which were aligned around issues other than slavery.
So unless the progressives can force a realignment along some new issue and subsume a major party, creating another party would just be handing a lot of elections over to the Republicans.
This is why lemmy was so vehemently against Jill stein and the greens even though most people on here agree with her politics more than kamala, because they saw her as sabotaging the democrats chances and handing the election to trump.
