It's like China is just that one country (aside from the Khmer Rouge) that every ML (aside from Dengists like us) agrees to hate on.
Fellow Traveler and leftypol uploaded videos criticizing them, the Shining Path hung up literal dogs to protest them, Maoists go all insane saying that it's some red fash social-imperialist nation because (insert nato propaganda here). And Hoxhaists claim that China was never socialist and that the only socialist nation ever was USSR before Khrushchev and almighty holy Albania.
What is it that makes China so controversial even among MLs? I get that it's not perfect and every AES state has their Ls, but jesus.
I'll also add that "nationalism" is one of those spooky words the West likes to trot out to beat the Global South with simply on the premise that because Western nationalism was an absolute clusterfuck (and here they'll usually point to the "nationalism as reason for WWI and WWII so it must be bad" gimmick which is agnostic of the Marxist discourse on the role of capital and imperialism in those wars), it must mean that Global South nationalism must transitively be bad as well.
Similar to how Western sexpats post pictures on Reddit of Buddhist swastikas trinkets in Asian flea markets and the comments use it as a sign that Asians don't care about the Holocaust. Yes, places like Modi's India show that Global South currents of nationalism can be warped into profound fascism and cultural chauvinism, but this should not be seen as the prima facie character of Global South nationalism, particularly for AES states.
In essence, nationalism in the Global South operates on a different register from how it is seen in the West and this distinction should not fail to be appreciated. The reason why the West itself downplays nationalism is because the entire bloc is now more or less subordinated to American hegemony not unlike how their propaganda once portrayed Comintern/Cominform Internationalism. Countries with flare-ups of nationalistic (or "patriotic") state character like right-wing Hungary interfere with the ease of coordination to Washington directives and thus are a distinctly problem child for US state interests, which is why nationalist currents are generally suppressed today in the West.
