In conventional narrative, the ideology on the far left of the horizontal spectrum is called Communism and the one on the other side is called Fascism or National Socialism.
Communists are opponents of private property and believe the State should own and control the means of production and that violence is both needed and just to reach Utopia. Whenever Communism has been tried, it has resulted in poverty, misery and genoice.
Nazis are opponents of private property and believe the State should own and control the means of production and that violence is both needed and just to reach Utopia. Whenever Nazism has been tried, it has resulted in poverty, misery and genoice.
How can two identical ideologies be both identical and polar opposites at the same time? It is absolutely obscure to me and should be to anyone with an inch of sense in their mind.
This has nothing to do with fingerpointing to purify my own ideology. It just happens to be that Leftism is evil. The further from the Left you get, the more peaceful will your society be. There is a reason contemporary Liberals position themselves right of Communism; they understand the lunacy of it and are not completely evil.
Edit: It is no coincidence that that scientist managed to get a re-written excerpt of
Mein Kampf published in that Marxist Feminist magasine - It sounded good to their ears and much in line with their reasoning.
