To be clear: I don't give a fuck if someone identifies as communist. I disagree (more in the vicinity of demsoc, personally) but people have had more impractical ideologies.

The issue is that dessalines et al are very much tankies. People who will say and do whatever it takes to say that china and russia are correct because both of those countries used to identify as communist (how long either actually was is up for debate). And that tends to manifest as actively supporting the invasion of Ukraine and the state sponsored ethnic cleansing by, among other horrors, rape of (among multiple ethnic groups) the Uyghurs
