Is there an example of what you would class as a true socialist government anywhere.You will find that is a deliberate ploy by the right, Pangloss. They use it as an insult, and have twisted the meaning.
The left really do need to find some way to distance themselves from it. Like Bernie Saunders and AOC saying what they support is Democratic Socialism. To most, that's still socialism.
Even Corbyn isn't a true socialist, and for that matter, neither are the Chinese.
