If the "alt-right's" goal is to turn the clock back to 1950, they've already lost, regardless of what happens in this election.
Times have changed, even in America today over 50% of children under 5 are now non-white. I think the majority of kids under 10 actually have already hit that threshold by 2017. That is the future of the country, like it or not.
People are just going to have to learn to live with another. There's no burying your head in the sand and trying to pretend it's 1950 again.
And racism is still a problem, most people are racist to some degree. They understand rationally that it's a stupid thing, but they still subconsciously project racist beliefs. We are not all the way there yet, get back to me maybe in 100 years.
We live in a modern world of instant connectedness (internet, smartphones), a global economy, relatively cheap transportation to anywhere in the world, if those things existed in 1850, you can bet society would look very different today too. Something like the two World Wars probably never would've happened.
