A useful example of an academic field creating a wall between the field itself and the politics of its members is the Goldwater Rule that psychiatrists are not supposed to publically comment on the mental stability of politicians. It is named after Senator Barry Goldwater, who objected to psychiatrists calling him mentally unfit to be president during the 1964 campaign. Goldwater made the very reasonable argument that those psychiatrists had violated their own professional standards by claiming to reach some kind of professional opinion about him despite the fact that none of them had ever met him in person let alone actually been his therapist. The Goldwater Rule protects psychiatrists by keeping them out of politics. Psychiatry may be very valuable in helping people but there is nothing in psychiatry that can tell you who you should vote for. Even if it turned out that psychiatrists were the most liberal people in the world, conservatives could still accept the legitimacy of their field as it has no direct bearing on politics.
This is why I find it amazing that anyone would want to eliminate the Goldwater Rule to better allow psychiatrists to attack Trump in their capacity as psychiatrists. To be clear, I oppose Trump, believe that he is a major threat to this country, and accept that he is most probably mentally unstable. That being said, I fail to understand how allowing psychiatrists to use their professional stations against Trump will actually benefit the opposition. How many people who currently believe that Trump is sane and support him will be convinced by psychiatrists otherwise? What is more likely is that Trump supporters will become more convinced than ever that psychiatry is a conspiracy designed to advance a liberal agenda. This is much the same as how many secularists are convinced that organized religion is simply a conspiracy designed to uphold conservatism. (Both of these groups may very well be correct.)
Critical to Trump's success has been a form of relativism. Beyond the specifics of any particular policy such as environmental control, Trump's supporters do not believe that there really is such a thing as an expert. This creates a world in which there are simply contending teams (warring religions if you will) with their contending sets of values. If this is the case then I want my side to win and can safely ignore any argument from the opposition. They are not arguing in good faith and any factual arguments they raise can be dismissed as distortions. Furthermore, there is no reason to ever question my own tendency to argue from values instead of facts. The other side is clearly worse so anyone trying to judge me must be trying to cover for their team.
