I've been trolling through the internet fever swamps and came across this intriguing statement:
"We reject the power inequalities and structural violence based on privileges of class, race, gender, sexuality, religion, nationality, ability, and age."
The usual round-up of victims, with a new one--"ability"? So having ability is a privilege that leads to "structural violence" (whatever that is)? Maybe this explains the Cambridge school system.
I can imagine that this group wanted to include people with disabilities in their coalition of victims. If disability is good, it stands to reason that ability is bad.
