I think it would be an error to regard that anxiety as a driver of mental illness generally. I see the big stressors as material insecurity, social/relational insecurity, and the various forms of violence attendant on those ills. I worry that narratives giving credence to the thought that gender ambiguities are somehow causal at the societal level distract from actual causes, which seem more rooted in our economic and social systems. But of course, reasonable people may disagree.
