"One of those interesting situations where countries that actually experienced authoritarian socialism (like yours) are far less supportive of its reintroduction than countries who didn't experience it" - you can't reintroduce system to the country that has never had it. In Poland it's reintrudction. In USA it would be introduction.
I am aware that there are plenty of leftists in west who think communist is good because it's in opposition to current status quo and they always want to fight with something and it's also in opposition to conservatives thinking. However from what I'm seeing on ther internet folks like that usually don't know what they are talking about, they rarely stop and think what ideas they preach really mean deeply and lead to in long term. I'd say people who "like" communism in west are 90% teens and young adults. They need to direct their young rebellion energy somewhere to fight status quo. And most probably they grow out of it within few years.
On the other hand, people in Russia and China have communist and collectivism ideas deeply rooted in their minds, these ideas have been with them for generations. The state makes sure that society sees communism as a good and rightful system. To achieve this, it relies on a massive propaganda machine that operates on every level. People are raised with the belief that collectivism and the subordination of the individual to the common good are what brought the country development and prosperity. These people study it, study their "history" and read books about it.
Essays on dessalines page are very solidly written, he has a lot of knowledge about these ideas. It would be much easier to write like that for a russian born (actually I'd say he is russian born but lived in USA or UK cause his english is very good, could even be born in USA but had russian parents, there are millions of russian immigrants in US) than western. He 100% is not American, cause he pretty much shits on USA big time.
