I have no issue with people criticizing Trump for whatever reason, patriotism or other. My issue is when someone who is a mental health professional uses that position to make a mental health criticism, they are using their authoritative position, unethically. It would be like a doctor saying a baseball player should retire because the fact that his running speed has been declining is an indication of ALS. Saying something like that, because the person saying it has some authority and expertise on the issue, has a larger affect on the perceptions of others, negatively affecting the reputation and value of the ballplayer. It would be different if a layman said it because he has no perceived area of expertise in the area. These people are using their area of expertise in an unethically authoritative way. That's what is really irritating to me.
Is Trump mentally ill? I have no idea, and what he writes or says gives us information, but it is very different than a clinical interview. I have had many clients that come to me with their parents telling me what their diagnosis is based on their observations. I've had them tell me that psychologist friends of them have told them what their child's diagnosis is. When I conduct the interview, quite often, the diagnosis is completely different. There is only one real way to determine Trump's mental status. Standard clinical interview. Anything else is just pure conjecture, regardless of the qualification of the person making them.
