I've been pondering this for a long while now and basing to what I've read from the execution of the "bourgeois" and Maximillien's party advocating for "workers' rights" now convinces me to hatch a firm theory that the French Revolution and the honchos behind it are the ones who inspired Marx, leading to the infestation that we're in today.
I have yet to strengthen this theory, but if you can help, when you have access on the papers of Robespierre and his allies during the French Revolution that would cite things about anti-whiteness, anti-masculinity, anti-Western values and anti-capitalism that would be wonderful. We can cross-check it with Marx's works and finally show people the demons that started this ideological tyranny known as Marxism.
Look into E. Michael Jones, he wrote about this and discusses it on his youtube/bitchute interviews. From his perspective, the enlightenment was the beginning of communism and all of these leftist ideas, and the french revolution was one of the first communist revolutions.
Here's one of his books that discusses this within the first 100 pages, but the whole thing is a great read.
