France became a pioneer in cuck culture for 2 reason, both linked with the aftermath of WWII
>FIRST REASON
First of all, the French communist party following WWII was pretty strong compared to other Western Euro Communist, rivaled perhaps only by the Italian ones.
When the Gaullists took power after WWII, the communist were numerous, and still armed in the countryside; the right had a short majority, but had to share the power.
While the commies left the Army or Police ministries to the right, they demanded control of the Ministry of Education.
In the long run, that was a smart decision, and France became pioneer in youth leftist brainwashing.
Take the Khmer rouge : Pol-pot and his group of close friends didn't learn their ideas in Moscow or Beijing. He developped his ideology and party while studying electronics in Paris; and you know what happened when he returned to Cambodia.
You know what happened when they came back to Cambodia...
> SECOND REASON
But worst than the official, Stalinist communist, FRANCE HAD THE MARXISTS (not called cultural yet, just regular marxists).
See, while the stalinist PCF had some patriarchal elements, and their sovietism was mixed with French nationalism, the dissident Marxists were as degenerate as they are today. They were banned from the PCF as "leftists", which for them meant "young idiots"
But without any solid structure, they thrived in informal small groups, and through entryism, propaganda and networking, they elevated themselves in the highest positions in the society; permeating the fabric of French society with their "cool", "intellectual" and rebelious ideas.
The entryism was particularly strong, they could influence every sector of the society without ever stating their end-goal.
Today, all of the former Marxists have coopted each other into positions of authorities, and many influential French leaders have a past in one or another marxist group.
This is especially true in Academia, News & Politics.
