Why do people either love or hate Trump?

I am from Canada, and I moved to the U.S. 6 years ago. I was never into politics in Canada, and most Canadians will not be introduced to American politics unless they actively search for it. I never knew much about Trump until I moved to the U.S., and at that time he was president.

One thing I have noticed, compared to any other public figure, is that there seems to be no in between when it comes to liking Trump. People seem to either love him or completely despise him. Essentially, from my experience, I've only met people who can either listen to him for hours, or can barely stand 10 seconds of his voice. Why is this the case? Most public figures will have people that love them, hate them, and then those that are somewhere in the middle. But there seems to be no middle with Trump.
