Incidentally, despite people portraying Huey Long as both antisemetic and antiblack, there is no proof for either. The only thing for antisemitism is having known Charles Coughlan, which is spurious. Lots of people today have met David Duke, that doesn't mean they believe what he does. He also tried with limited success to actually make black and white schools have an equal curriculum, which given that this happened multiple decades before desegregation must have been dangerous as fuck.
I definitely think we do need to have a deeper understanding of racism beyond "you is a wrongthinker", which is how a lot of people lay it out.
One article point out how some Silicon valley guy was slapped on the back as "brave" because he came out on twitter going "racism bad yo, hire more diversity". But the point is, for his in-group that's the expected thing to say. It's neither particularly "brave" nor all that clever. Basically he opened his mouth and the expected sounds came out for his social sect, doesn't make him better than anyone else.
In my view, the beliefs of individuals are irrelevant. Lots of people have this image in their minds that if we just debate down/beat down every racist person in America, we'll have less racism.
Yeah...no. There are three-hundred million people in this country, and maybe about a tenth of one percent of those people have the sharpened self-awareness and humility necessary to change their minds because they lost a debate. All of the arguments in favor of tolerance for LGBT have existed for a long, long time. That isn't why there's more tolerance now. The recorded largest reason why is because people know friends or family who came out. Experiences, not arguments, alter people's beliefs. Seek trends on the large scale.
This is an aside, but according to Gallup in 1945 10% of Americans supported legalizing same-sex marriage. I'd like to know what the deal was with that 10%. Obviously some of them were personally affected, but given the number of people in the modern era who are bigoted because of denying their sexuality I'm not so sure that makes up this whole group. Just an interesting thing.
Know who is a Senator from the state with the most rural voters? Bernie Sanders.
Vermont is also generally wealthy and has a functional local government. The connection between these things and being the people who voted in Sanders is real.
The median household income in the US in 2012 was about 50k. Obama lost voters in households with less then the median income by 5 points. He lost voters in households with more then the median income by 20 points. More then half of Montana voters were in above median income households.
If the Dems had a good rural program they should expect to win the households with less than median income by 45 points. There's no good reason for the poor vote to be something the Dems should have to fight for.
This cannot reasonably be boiled down to religion and racism. People are...rational is the wrong word. They do what's enticing to them. I don't think living outside cities exposes people to bigotry particles, and I definitely don't think such a rag-tag ideology can hold itself up without professional curating. Our concious thoughts spin out of more basic things, common experience building ideas.
