I think your opinion of him shows your biased towards him. He attacks people who speak out against him. He assigns child like nicknames to his opposition. He would threaten to beat someone up and take their lunch money if he could, but his bone spurs don't allow him to. Okay, that last example is a bit far, I'll admit. But I see him as a bully. Look at how Obama handled his critics. He simply ignored them. He did his job. He didn't tweet about them. He did his job and nothing more. Sleepy, crooked, low IQ. Come on. Donald Trump does not act like an adult. This is what happens when you're born with a silver spoon in your mouth.
The fun thing about his assigned nicknames is they can almost apply to him. For example, "Sleepy Joe." Trump needed a golf cart at his first G7 while the rest of the world leaders walked around. He generally starts his day around 11 from most reports and that's with executive time aka watching Fox News. Crooked? I'd call someone crooked if they stole from a charity, especially if that person claims to be rich.
