Even if you adopt hardline Marxism-Leninism-Maoism as an ideology, the modern state of China has applied so much pro-capitalist revisionism to it that it's a shell of its former self. Today, Maoist parties are suppressed in China.

I'm not a Maoist by a long shot, but I can at least appreciate the fact that the ones shouting "revisionism!" the most are the ones who have most bastardized their own texts.
