This is an interesting point, but he's also done and said a number of things that indicate a level of comfort with his supporters committing violence that is entirely inappropriate for a leader of a democracy, and suggests that he wants a paramilitary loyal to him. Those are exactly the actions of an authoritarian. "Stand back and stand by"

There's also been a focus on personal loyalty in high office that is also unseemly in a democracy, and has caused problems for the USA in the past too.
