Not sure they are bad people per se... but where do you draw the line?

Sure Hitler improved the German economy, does that make it defensible to support him?

This is the fundamental question in nationalist movements that are driven by ideologies, tribalism, and cult of personalities... instead of real facts backed up by science and data.

Given that provably almost nothing Trump ever says is even true, how can these people know he is the best person to govern? If there are no facts, it is just beliefs... and that is incredibly dangerous.
