I think the key heuristic of leftism now can be summed up in two words: instinctive perversity.
I think most people have an inborn sense of what is right: treating people fairly, not harming children, the importance of family, not having a disgusting appearance, etc.
So the left-wing training consists of getting people to intuit this natural morality and then … go against it.
Probably not one in 100,000 leftists have actually read Gramsci or Marx or the Frankfurt school or whatever, but they instictively turn like a flock of birds towards what is most degenerate.
But that puts rightists in a logical trap: if rightists make a fuss, then, as the Zman says, leftists will get off on that. But if rightists don’t resist, then the degeneracy will probably just march on anyway.
Probably the only way out is through some sort of … (*wracks brain for nonfedposty language*) … non-democratic means.
