The liberal theology that is rooted in the desire to be open-minded and intellectually sophisticated is completely different than the liberation theology that is shaped by the actual needs of marginalized people.

The reason that liberation theology tends to become intersectional is not because of liberals looking for -isms to define themselves by, but because marginalized people have built actual, real-life coalitions with one another for survival.

And today the vanguard of the racial justice movement are queer black women. Queer people have historically been on the front lines of radical movements because they weren't culturally accepted elsewhere.

Furthermore, systemic evil is often shaped by interlocking ideologies. For example, rich white people justify their wealth by adopting a sexual puritanism that slut-shames blackness and makes heteronormativity the definition of morality.

White supremacy is always also misogynistic, heteronormative, and contemptuous of the poor. So intersectionality is not the trendy invention of liberal humanities professors, but the natural alliance-building of all the victims of white supremacy.

So when liberation theology Christians critique the inadequate intersectionality of a liberal Christian who's cherry-picking a few -isms in his platform-building project, it's not because they're "intolerant" and "exactly the same as the Right."

It's because their theology isn't a parlor game but an actual quest to survive and having a robust coalition of marginalized people who refuse to leave anyone behind is the best strategy for survival.
