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.
In some ways it was. One of the biggest forms of early Communist type thought was put into practice during the 1871 Paris Commune. France has tended to be the place where radical egalitarianism has been fostered.
I would recommend reading some Nietzche as well, because from his writings we know that this "Inversion of values" has existed for a long time.
I wish Nietzche dropped names in his works on who these people are instead of talking the pseudo-intelligent holier-than-thou route.
He certainly does in the Genealogy of Morals.
