Are you in tech or some other field that doesn’t involve interacting with different socioeconomic groups?
Most of not all states guarantee some “interesting” encounters if you leave the cities. In California I have seen Confederate flags flying, met neonazis, and plenty of Trump supporters. Trump got over 34% of the vote in California, almost 39% in Washington and over 40% in Oregon. Those percentages are not a majority, but I think it sets a floor, since Trump supporters are not exactly trash talking the US.
I have spent a lot of time doing canvassing and other activities that mean I encounter people with very different ideas, so that would definitely explain the different experience.
If you’re going to accuse me of lying, at least have the decency of doing it in a reply to my post. I lived on the East Coast and traveled up and down some, then I moved to the Midwest, I got into politics and canvassed in several states plus I went on a few road trips for fun. Then I moved to the West Coast, which somewhat limited my ability to go on road trips to other states, but still, I went as far as Colorado, I spent a month there doing backpacking and visiting a few places like Denver and Aspen.
Why do you think it is so unlikely I could visit 3 states a year?
