Slop.

One of the biggest things that makes me certain communism is the way forward is every single argument against it is an argument from ignorance or racism. I've never heard an anti-com argument that doesn't boil down around 4ish "answers."

1: "They aren't white, so their achievements don't count" (Usually cloaked in implication rather than outright stated, but there's always an air of "If western europe couldn't do it, no one could." (Usually with bonus mentions of the Nordic countries for good measure))

2: "My grandma's friend's dentist used to have an egg monopoly and they tell me gommulism is bad." (Usually said by people who have rejected every single survey and statistic about socialist countries, but a personal anecdote is obviously far more correct than the aggregated opinions of thousands or millions)

3: "it isn't real socialism because I've got my own personal definition of the term that is inherently contradictory and impossible to meet." (Usually used by western "leftists" who mask their western chauvanism behind impossible standards. Usually overlaps a lot with the first one.)

4: "Saint Karl Marx of Orthodox Marxist Faith said that this wasn't real socialism" (See also: Trots making similar claims with Trotsky.)(Pretty basic stuff here, treating communist theory like some kind of religion or infallible Truth rather than a scientific analysis of class structure and society. The Holy Prophet of Marxism said this, therefore you are wrong and following evil false prophets, like Stalin. Bonus points if they claim that Marx said this or that, when he actually said the exact opposite in his writings.)

I'm sure there are more, but those are the only ones I can think of off the top of my head.
