Social Democrat apologist claims that the German Communists did ‘nothing’ to stop Fascism

Here is a commentary from the author:

The SPD, a party of social democrats and democratic socialists, had a fruitful period of cooperation with the KPD, the Communist party…

… until the KPD received marching orders from their new boss in Moscow in 1928, the newly ascendant Stalin, to refuse to cooperate with the ‘social fascists’ of the SPD, under the bizarre notion that the Weimar Republic collapsing under the weight of the far-right would let the KPD smoothly assume power, as though the army and paramilitaries were already communist instead of, you know, conservative as fuck.

Time for another history lesson:

It is wrong […] to assume that the KPD devoted all of its resources to a fight against the SPD and neglected the [Fascist] threat. On the contrary, most of the political violence practiced by the KPD during 1928–1933 was directed against the [Fascists], not the [Social Democrats]. It is also incorrect to assume that the divide between the KPD and the SPD was entirely motivated by the orders of the Comintern.

Certainly, the Comintern heavily influenced the KPD’s course of action, but deep divisions had existed between the KPD and the SPD from the very day that the KPD became a political entity. Further, the differences between the two parties were not merely ideological. KPD and SPD membership came from different economic spheres, they lived in different neighborhoods, and they experienced the Weimar Republic in different ways.

The SPD, for much of the Republic’s existence, was one of the main parties of government. When the KPD accused the SPD of Social Fascism, they were not targeting another radical left party; they were focusing their criticisms on one of the most powerful political entities in the Republic.

Related to this, the SPD had in its position of power pursued repressive tactics against the KPD. Thus, the KPD’s view of the SPD as social fascists was not merely the result of ideological dogmatism but was in fact shaped by the actual experience of the KPD in the Weimar Republic.

Oh, and a funny thing: the liberal nationalist Gustav Stresemann once seriously proposed collaborating with the SPD:

[A]s Jonathan Wright has argued, the Kapp putsch made it clear to Stresemann that any attempt to restore the monarchy was bound to end in civil war.⁴⁵ It was Stresemann’s pragmatic approach to the Republic which brought the former implacable enemy of socialism to the conclusion that it was necessary to bridge the gulf between his own party and the SPD, the two parties representing the conflicting social and economic interests of industry and the working class.

At the [Deutsche Volkspartei’s] Stuttgart party conference in 1921, Stresemann suggested [that] the DVP should return to the government coalition. In reply to the reproach that in order to do so the DVP would have to make concessions to the Centre and the SPD, Stresemann again referred to Bismarck: ‘I ask you to go back in German history, to consider the greatest statesman the world had in the nineteenth century, Bismarck. Were his politics anything other than the politics of compromise? […] Was this policy of the achievable not a hundred times more national-minded and forward-looking than the policies of those who felt the necessity to attack it?’⁴⁶

Stresemann’s willingness to co-operate with the Weimar coalition parties after 1920 was never forgiven by the nationalist opposition.
