I think PTSD is an example of pathologizing normal human variation and normal responses that happen to be inconvenient or undesirable to TPTB.

PTSD looks like a perfectly sensible Darwinian adaptation conferring hypervigilance on animals who have escaped predators. And human society contains many sorts of predators. Those who have been victimized by human predators and have developed a normal, natural brain response are seen as the "disordered" and "disturbed" ones. The human predators who caused this "disturbance" are neatly off the hook: all the focus is on the "mentally ill" victims, not of human predators, but of this abstract condition called "PTSD".

It sounds to me exactly like rape culture at work: blame the victim and exculpate the rapist/predator.
