The same can be said of National Socialism: "Gas chambers were a bit excessive, but overall social harmony, strong leadership, self-reliance and state control over key industries is a critical voice against an unrestrained free market system", etc.
National Socialism could serve a similar purpose if it weren’t based on racial theories and fear of Jews and a type of nationalism that’s foreign if not repulsive to most westerners and especially Americans. It’s too polluted with that stuff at the theoretical level to be kept around. Communism, on the other hand, looks great in theory. It’s all about the universal brotherhood of man, liberation of the individual, equality, peace, justice, etc. Its moral aspirations come straight out of the Judeo-Christian tradition (while distilling out inconveniences like God and the Bible) and so it has access to lots of familiar receptor sites in the western mind. For the West, communism is like clinically pure heroin whereas National Socialism is street junk tainted with battery acid.
