Here is a simple summary that you seem to have not understood - Some professions should generally be subordinate to politics, but not necessarily to morality. For example the military. If a general tells a private to kill someone, generally the private should act. The private should not say "But that contradicts my 3 months of experience ...". Other professions should not be subordinate to politics. For example the Soviet Union had a mental illness called something like "failure to understand the wisdom of communism". If you are going to see the human mind through a racial / political / religious / commercial /etc lens, then you need to not be a psychiatrist, and instead be a racist / politician / rabbi / businessman / etc Its enough that most psychiatrists are incompetent. Not necessary they should be politicians too.
