"Just resist psychopaths" is an ableist, reductive paradigm. Of course many people can't just resist. People have families, care responsibilities, and many are indeed conditioned to accommodate.
Would you say that it's also ableist to ask people to "just resist fascism"? After all, many people are indeed conditioned to accommodate fascism. Or pick another -ism you prefer.
Yes, that hews into the same notch. One cannot simply resist any form of oppression, there were/are only a lucky few who had the motivation, ability and resources to do so. If you are one of those and would gladly take a fight against the world to make it better, then be mindful to not hastily generalise from your position.
Camus and Sartre would like a word. I prefer their worldview.
By your own argument I don‘t even need to give a good reason. I‘m not able to give a good reason, I prefer their philosophy of being responsible based on your notion of not having the ability to see it any different.
