We're just far enough left to see that "hierarchies aren't self justifying" extends to reality too. We don't accept realist defeatism. Realism is an infant ideology of avoiding responsibility for reality, and saying "it's not my fault, it's reality".
Just because authoritarians pretend that the status quo is inevitable and immutable doesn't mean that reality itself is a human invention made to justify it and other assumptions.
Likewise, conflating defeatism disguised as realism with the concept of reality itself is not just a giant leap of logic. It's a giant leap AWAY from anything resembling logical thought.
Reality isn't fake because it's defeatist, it just happens to be both fake and defeatist. It's fake because it was invented by rich white men in the 1600s to justify colonialism. And it's defeatist because most people today acknowledge those rich assholes were wrong about how the world should be, but not about how it is.
[Reality is] fake because it was invented by rich white men in the 1600s to justify colonialism
Damn. That take is just as batshit insane as the right wing's worst conspiracy theories! Not anywhere near as malevolent and harmful, of course, but just as divorced from any sense.
And it's defeatist because most people today acknowledge those rich assholes were wrong about how the world should be, but not about how it is.
Acknowledging the current state of affairs as existing is not only not defeatism, it's absolutely CRUCIAL in order to effect any positive change.
Saying "it is" doesn't equal saying that it has to be. You can't effect positive change if you don't first acknowledge what the things that need to change are rather than pretend that it's all a shared hallucination.
Sure I can effect positive change while believing the bad stuff exists only in our heads. Our heads are where we live! Of course I want people to have better illusions in their heads. For example, if Trump wins then a bunch of queer Americans will experience a subjective sensation of being oppressed. That's horrible, so I'm asking Americans to vote for Biden.
