While it's true that you can reach out and have a meal, share a laugh, with a Trump supporter, I don't think that will do anything lasting or good. Trump supporters are, in my personal experience, willfully ignorant. They make general statements (particularly about the poor state of the US and Obama's failure) and cannot back them up with supporting facts. They get indignant and threatened when asked for facts. They ignore evidence of his lack of personal values.

Yet the doom that faces America is very real, and this is really the cause of their emotions. Intuitively they know we can't consume so much without producing it. If we offshore production, we must eventually offshore consumption. Chinese workers earning $5 a day, Chinese factories paying no attention to the environment or workers rights, this is really the ONLY problem we need to address. And the liberal elites don't care, because they don't make money making things, and never did.

Are you a liberal elite wanting to heal the divide? Build a factory in the USA. A real, physical factory that builds real, physical things. And if you do the math and realize you can't do that and compete with China, then fight like hell to punish Chinese producers for playing the game by unfair rules (e.g. impose tariffs to at least bring the price up to what it would be if they paid their people a living wage, benefits, and protected the environment).
