The way he treats other people, mainly. Admitting how he hates others, mainly other nationalities and those of different religions. This morning, I saw a video of his badmouthing the press, telling one person that he likes her and that she's pretty, then telling another that he hates her and that she's stupid. That's not right. He thinks he's above everyone else, and he treats others like crap. I thought this was America, the land of the free. If he takes over, this country will lose it's definition really fast.
That's just my opinion, of course, from the years I've been watching him and his actions.
