Quite a good distillation of alt-right thinking.
I think the American people voted for Trump not due to a sophisticated understanding of his alt-right platform, but rather a gut level instinct that something is wrong with the direction of the country. This article pinpoints the idea: borders (or boundaries). America feels like it's headed toward a border-less existence, in terms of geography, in terms of capitalism/jobs, social behaviors (bathrooms), and identities. The Alt-right favors reinstating borders into our lives and I can't say I totally disagree.
