Absolutely nothing. You didn't waste 15-20 minutes of your life, like I did, before I gave up.
In my limited experience (i.e. based on my ignore list), the same people who tend to like Trump tend to believe in all kinds of conspiracy theories, some downright ridiculous (remember birtherism). I don't think it's a coincidence. I think it's a matter of poor judgment (with all that that implies). They simply lack a basic intellectual skill (and many times a basic level of general education that would allow them to see through ridiculous claims, or to attribute them the appropriate low probabilities).
Btw, I am the kind of doctor who will listen carefully even to "crazy" patients, because some of them are definitely not.
