What exactly caused the "Anti-Woke" movement to form?

Nevermind the terminology, I'm having a hard time tracking exactly how we got to the point where we're undoing several years worth of progressive policies. I'm pretty sure we were on a fairly straight path towards equality around 2010; what exactly happened to spawn a massive group of people with the mentality of someone from the 1960s large enough to swing elections?

I'm rather new to this whole thing, and every time I google it I get a bunch of people complaining about SJWs and whatnot.

I'd normally just put it off and say this is just history repeating itself, but I recall that the last time something like this happened, it was the result of a war going horribly wrong, or a massive economic downturn, or something else that left a lot of disenfranchised people desperate for change and they ended up electing some crazy person into office who then tried and failed to establish facism. This has happened more than once apparently.
