I agree with this. I know quite a few who voted to leave, and they aren't racists. I think they're wrong, but your point about the constant growing bureaucracy of the EU is the most important one (as well as the history of the member states). As it grew larger and larger, people became more and more disaffected. I can't say the decision to leave was a good one, but I wouldn't paint those who do think that as racist, stupid, or anything else. There were valid concerns on both sides, and though I think staying in the EU would have been a better result, you have to respect the fact that we have left.
