If you don't think that racism isn't at the heart of why people despise Trump, just look at the numbers. Black people, even those in poor southern states, voted almost exclusively for Democrats despite Black people suffering the highest rates of poverty in those states. Forgive me if I lump all white southerners together, but my god, the good ole boys of the south fought a war to keep black peoples enslaved in the 19th century, they then fought viciously for discrimination of Blacks and against their civil rights in the 20th century and in the 21st century they voted for a party that is almost 100% white and a party that actively gerrymandered districts to disenfranchise black voters. Forgive me if I question the intention of the well-documented white southern voter who, for some reason, votes almost always the exact opposite of their Black neighbors. Why would this be? Does their history of racism have anything to do with it?
There are many, many white people who live all over the US (south and north and coasts and Midwest) who care deeply about ending racism. If you aren't racist, but voted for a man who Federal officials found evidence had refused to rent to Black tenants and lied to Black applicants about whether apartments were available, among other things, you really don't give a shit about Black people in America.
