I feel like we had this conversation before at some point lol... I will summarize my point of view on it and then probably dip from it:
- KPD in 1917: We're going to seize all the guns and overthrow you and make Communism because Communism
- German government + German people and unions + SPD: Fuck no you're not (gunfire)
- KPD in 1918: Wooooooowwwwwwwwww okay fuck you, I see how it is
- Germany: Hey KPD you still can have a seat in government, you have to get the votes though, no shooting your opposition, no seizing
- KPD: Woooooooowwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
- SPD in 1932: Hey we're going to make an alliance with you because this guy is dangerous, we don't care about the whole "trying to overthrow thing" that happened a generation ago
- KPD: Woooooooooooooooooooooooooooooooooooooooooooooowwwwwwwwwwwwwwwwwwwwwwwwwww
- Hitler: (wins)
And then much later:
- KPD (ones still alive): Hey we're going to need all the trade unions to do what we want instead of what the workers want, because that's leftism
- Germany: Lol fuck OFF
That is my summary. I realize you may have a different one but I don't think I really want to get in an extended argument about it today. But yes, Germany in the 30s is a relevant example on this topic, I absolutely think.
(Oh, also, the KPD was being murdered by the Nazis with the aid of Stalin. The KPD was coordinating with Stalin, and he was selling them out because of course he was. I have absolutely no idea where you got this idea that the SPD was involved in what Hitler was doing to his opposition.)
