How did it go for the liberal centrists who said "Let's just trust the process and hope our completely dysfunctional electoral system will keep the Nazis at bay"

Also it is pretty fucking gross to characterize the KPD position as "letting fascists win" considering that the centrists and liberals constantly appeased the fascists whereas the communists had been fighting them for years, and died doing it, and Thälmann, unlike the liberals, was murdered by Nazis
