I don't disagree about this, but from my perspective it is taking place because after decades of good faith attempts at asking for improvements, and those largely being refused in practice by people who don't want to give up their privileged position, a lot of folks are tired of begging for their humanity to be considered. The onus is on the historical oppressors to start playing nicer first.

The Black Power movements of the 50s and 60s came about because decades of trying to assimilate and be seen as "good citizens" was getting Black folks absolutely nowhere. Feminism is becoming more radicalized and militant because 60 years of asking nicely hasn't actually gotten us very far. On paper, it has, but not in people's actual lives. As my husband the lawyer pointed out, women still have to sue everyday in order to enforce their legal rights. Black folks too...

As MLK famously pointed out, "Freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed." Pretending that isn't actually so doesn't change the fact that history bears it out. Of course demands for freedom come with backlash - MLK was murdered for demanding it - but his loud, persistent, and unwavering demands also got encoded in the Civil Rights Act of 1964.
