Apologies for an clumsy post, on the tablet.
US democracy is enough of a farce without involving medical professionals in the constitutional process of election. It privileges maybe two groups that have political interests and would expose the private lives of candidates in ways that have no bearing on their ability to serve as president but might affect electability "gay dream in High School? Noparino!" Any opinion offered with examination probably over several sessions would be meaningless, but you want candidates subject to as many doctors as feel like having an opinion about him? Utter nonsense.
As for the garbage about responsibility of professionals, the professionals have decide they have a responsibility not to fart out stupid assessments for the sole purpose of political character assassination. Just to spell it out, psychiatrists have after sober reflection decided what you suggest is unethical.
As as an engineer if you feel compelled to condemn buildings you haven't even inspected maybe consider a career change: this sort of idiotic and unethical behaviour wouldn't be appreciated by your peers or potential employers (litigators OTOH...). Don't become a cop though, accusing people you've never met of rape is frowned on in that profession.
