You are missing a key point of their worldview: *Everything* comes down to 'critical theory' in one way or another. Whether you are focusing on race, sex, or anything else that can be the subject of criticism the outcome is the same.
Women CANT be sexist, because 'men' have more privilege and historically have less authority. So as the oppressed sex, they can't be sexist because they 'lack power'. So statements like "I hate all men, they are stupid violent thugs" are not viewed as sexist.
The same goes for race -- while you didn't call it out specifically, it's the exact same mindset. It doesn't matter if a BIPOC person literally kills a White person and says "I hate all white people and I killed them because they are white". This is not racist to these people, because that person supposedly lacks 'power'.
They (hypothetically) had and utilized the power to kill, but that isn't 'real' or 'institutional' power, so it simply does not count.
Both concepts are equally stupid and fly in the face of reality. And the inevitable outcome is CONSTANT conflict.
The conflict stems from being 'critical' of these different institutions and people who have 'power' or 'privilege' -- but the cycle never ends, so even if you manage to remove all Men or White people from existence, a power vacuum will exist and the criticism will be levied on whomever fills the role.
It's the perfect way to perpetually conquer and divide, where you get to claim perpetual victim status, while ensuring the voice of the majority -never- matters because of their supposed 'institutional power'. The end result of this thinking will be less tolerance, less diversity, and more asinine stuff like this python situation.
They mean EXACTLY what they said, take them at their word.
