This seems like it's giving them a lot more credit than they deserve. Most Trump supporters aren't just racist. They also hate the poor, anyone who is not strictly heterosexual, people from other countries (even the white ones), anyone who tries to work towards any kind of equality, women in general they really hate... It's a veritable cornucopia of hatred and voluntary ignorance!
Trump supporters: “immigrants are stealing our jobs!”
Also Trump supporters: “immigrants are lawless and living off the dole!”
While this is technically possible, I’d like to know what the Trump supporters are doing if they currently have no jobs and aren’t on social security. And where they come from, as everyone immigrated at some point, even the Aboriginal Americans.
