Honestly, this shit needs to stop. Acknowledging that some fascists have been good at something at some point does not detract in any way from being anti-fascist.
If you claim that fascist are dumb, stupid and can achieve nothing, what do you think the masses will think about your message when the fascists turn out to be competent? They will wonder what other things you are wrong about.
So I say to you: stop being a fascist enabler.
Does that thinking extend to german citizens during 1930-1945?
