And to the assertion that violation of that premise created yet another class of political prisoners.
While moderate members of the anti-asylum movement were willing to concede that psychosis might pose difficulties for a few individuals, they insisted that society had no more right to force psychoactive drugs upon mental patients than it did to hold down diabetics for insulin injections.

The replacement chosen was an untested, less costly treatment model: the community mental center.
