I'm not particularly an undying supporter of China but I've noticed that western communists usually take a hard pro-vietnam stance and entirely blame China when the reality is not so clear cut if I'm going to be fair to both parties here (I think its because they secretly believe china is revisionist for adopting market reforms, not socialist for spliting with the soviets, or imperialist for attacking vietnam) but I dunno I don't understand western communists and their weird ideological inheritence.
