Anybody associated with it, advocating it or promoting it will be suspect for the rest of their adult lives. They have demonstrated they are not trustworthy people. They have demonstrated they are not honest people. They have demonstrated they are not sane people. They are discredited for whatever remains of their vulgar, banal and pathetic lives.
