Their ultra-leftism towards China is an unfortunate thing that I have noticed, and it is always annoying to see (I know that Maoism is not a purely western phenomenon and was in fact "synthesized" by Gonzalo and the Peruvian Maoists, but I swear, western Maoists just feel like armchairists).
Edit: Why did this get so many upvotes? I am a bit surprised haha.
