The only one of those things that are radical are historical injustices compared to the social expectations of today.

Inequality isn't radical. We've been doing that shit since the dawn of man.

Climate change isn't radical, at least not by the perspective of a single human lifespan.

Radical, transformative justice is bullshit skip-the-line mentality. Change is slow because people are slow to change. The only REAListic change comes from iterating from one end of the problem to the next, moving on only when enough people come to accept it. It's the whole boiling a frog thing.

Throw a frog into boiling water and he jumps out. Put a frog in water and slowly boil it with him inside and he stays.

Radicalization just begets more radicalization. It's not a good thing. There are always people who will step up to the challenge of extremism with their own flavor. Just look at the capital riots - the radical right's version of "I can riot too" only ends up escalating everything.

Minor reforms over time in the direction of justice is how justice gets done. Even big reforms only work when you've been mentally prepared for it by minor ones. The only reason you weren't raised a racist prick is because those minor reforms over time pushing it out of style.
