The thing is, the disabled are a population of enraged people. The disabled are carrying a deep rage because not only is ableism embedded in nearly everything in our world, but people without our vulnerabilities are hostile to making anything better for us. Also society does not accept our rage.
I agree that embedded ableism is ubiquitous. I also want to tell you that I hate that and, if I am not an activist, I *always* support actions to combat it and try to be on your side.
