Some would call it "cultural Marxism," but the bottom line is that there is no such thing as a legitimate social justice movement in the west because by law all people regardless of their ethnic circumstances are equally protected. You could say that SJWs are rebels without a cause, but I would point out that "social justice" is not their real cause. They aren't really interested in equality, they are interested in control.

There is a classic playbook for communist sabotage of a target society, and one of the first tactics is always the destruction of that society's history and symbols. When Mao Zedong announced the birth of the "Cultural Revolution" in China in 1966, his goal was to disrupt growing discontent among the Chinese people with the broken promises of the communist regime. Only 8 years earlier in 1958 Mao had initiated the "Great Leap Forward," which was a purge of his political opponents as well as a massive population reduction program that used food as a weapon. After the deaths of over 65 million Chinese citizens, Mao sought to redirect public anger by scapegoating a supposed conspiracy of "capitalists and imperialists."

The Cultural Revolution was essentially a nationwide witch hunt spearheaded by rabid and ignorant children; people easy for the government to manipulate and exploit. They scoured their own towns and cities as spies and enforcers for the CCP, looking for any signs that their neighbors were part of the conspiracy to disrupt the communist collective. They held tribunals and struggle sessions where anyone who said the wrong thing or who angered the wrong person was publicly humiliated or even murdered as "insurrectionists" by a mob of communist zealots.

Most importantly, the Cultural Revolution was used as a means to utterly destroy any remnants of Chinese history before the commies arrived on the scene. Museums and universities were raided and ancient artworks, documents, books and historical parchments were burned in pyres. Historians and people with knowledge of the Chinese heritage were marched up and down the streets and chastised as enemies of the people. Statues were torn down and entire buildings razed to the ground. The communist system cannot gain dominance without two things – Rule at the barrel of a gun, and complete control over cultural products and information.
