Personal agency is anathema to SocJus. The solution to the problems of the world isn't to give more power to the oppressed, as that would be victim blaming. It blames the issues that arise from unequal power on the side with all the responsibility: the privileged. Patriarchy? Men’s fault. When women support it, we say they’ve simply internalized the messages of men, and then condescendingly absolve them of any responsibility or agency.There's many things one can say about Jordan Peterson, but like him or hate him he stands a chance of potentially stopping some taking weaponized autism a bit too literally. His vanilla messages about self-worth, self-control, self-responsibility and so on are as harmless as it can get.
Also how even basic self-help messages like sort yourself out, take control of your life and live freely are like poison to Resetera, as they need to be told what to think, who to shout at and who is responsible for their failings in life.
On a personal level, SocJus erodes a person's sense of agency, since it sends the message that not only can't they affect change, they shouldn't. They generalize their own lack of agency and feel stuck at the bottom (top?) of the suffering ladder. On a more interpersonal level, it's another way of absolving one of any consequences of their actions or the political responsibility to act to change their own condition.
