Yes, but at a time when social democratic parties in europe hadn’t quite formally formed or split into discernable socialist factions. The Social Democrats in Germany were in active coalition with monarchist anti-republic paramilitaries and had inherited the government from the abdicating kaiser. The KPD didn’t exist yet, and this was technically an internal critique of the Social Democratic Party of which she was a member.

At the same time, the Social Democrats in Russia included Lenin.

At any rate it isn’t worth giving the freikorps a pass by omission when unearthing conflicts about the SPD.
