some person, who at least knows what socialism is, even if they're not the most well-read in the subject,
some way better read one, but thinks state control of enterprises suffice and trusts the state way too much as long as it has hammers and sickles,
some capitalism fan, who thinks socialism is evil, and that constructon company CEOs are workers, but underpaid office workers are "elites".
Rarely you get a very well read one, who understands their stuff, or the old Soviet bloc ex-communist, who switched because the local far-right party started to be very concerned about "work morals", and also think the construction company CEO is a worker and "against the elite".
The problem is the way that most of those communism perfect people inform themselves. They usually know a lot of stuff about a certain topic where they can argue anyone to deth who doesn't know as much about a topic. And because they know that much more than the other person they can use wrong statements that sound right in the mass of correct information. Then you get people who know everything about Kuba and are 100% sure it's a democracy.
