several dozen fucked up joints in a trench coat

With sick and disabled people physically and psychologically distanced from them, people who are well and non-disabled have detached themselves from the immorality of their own behavior. "Return to normal" frames indifference to suffering as a morally neutral position and public health as a matter of personal preference. But there is no neutrality in the individual actions that comprise public health; they either cause harm or prevent it. Segregating the "unfit" from the "fit" is not a matter of debate. It is an abomination and a core tenet of eugenics.
