I will try to make a short expalantion, but it's a long piece of shit.
Basically the soviet union wanted to spread communism over the world, but after the failed attempts in cause a "revolution of peasants" in western countries, one man realize that it would never happen because the live situation in western europe is just too good, way different from the life of peasants in imperial Russia. So instead of instigate a revolution, they needed to work from inside out, this plan was called the long march.
After the recovery of the Soviet Union post WWII, they started to infiltrate education institution and cultural spheres with agents. Most people did not even realize they were being manipulated by literal KGB agents, and genuinely thought they were doing the good.
The US was not oblivious to that, and started his own campaign to make leftism in the west a "faggot ideology", in a way that no one would want to join.
After the high of the cold war, the Soviet Union got tired of this bullshit, and started to end their cells all over the world, and when it finally collapsed, the chain of command simple was not there anymore.
Without orders, the leftists started to look for their own justice. The retarded, the negro, the women, the fat, the ugly, the immigrant, and shift their economical politics (that were hand written by literal soviet spies) into being just liberal nigger lovers.
