To break it down to its simplest terms- I hate him because he spreads hatred.
Hatred of blacks- he’s the guy who had staff hustle black employees off his casino floor whenever he came down. He’s the guy who spread lies about Obama’s citizenship, who demanded that the innocent Central Park Five be executed, who continues to disparage judges who happen to be black.
Hatred of Hispanics- all the crap about the border and Mexicans sending their rapists, murderers, and drug dealers. Deriding judges who happen to have Hispanic heritage. Separating immigrant children from their parents just to be mean.
Hatred of Women- attacks on Hillary, the grab them by the pussy line, buying Miss Teen USA pageant just to get an excuse to walk in the dressing room of underage girls, the callous lines about Mika Brzenski, I could go on and on.
Hatred of Disabled- mocking the reporter with palsy.
Basically if you’re not a white Christian heterosexual non-disabled male Republican, he hates you. Back to him, what’s not to hate?
