Remember, the social Democrats sided with the Nazis over the socialists. They’ve done it every time they’ve been given the opportunity, and will continue to do so as many times as people fall for their shtick.

I think the difference is, you’re saying the communists were infighting. The communists were United, they had their internal conflicts, (direct action vs parliamentarianism) but they were together. It was the CAPITALIST Social Democratic Party that murdered them. CAPITALISTS murdered them. Not other communists. Bernie Sanders isn’t a communist. AOC isn’t a communist. Neither was the SPD.
In other words, yes, you are. I almost wish you could see how funny this is from the outside. You just don't get it at all, do you?
Gustav Noske, the "Bloodhound of the SPD", used Freikorps (proto-fascist and/or monarchist) militias to kidnap and murder communists, who at the time were more influential than the SPD in many parts of the country.
And this should inform modern political theory because?
