Nice annecdote. Here's another one: I work in the IT industry in the UK. Not one of my current or past colleagues has mentioned any desire to leave the UK due to Brexit, and not one of them is a racist zombie either.
How sure are you about that? I was surprised by the number of people who have been holding some unpleasant opinions secret forever, and then felt safe to express them for a short while following the Brexit vote. It seems to have become unacceptable again, but it turned out more people than I realised were holding these views.
I regularly see people mouthing off on forums about how they're going to leave their respective countries because they're not happy they didn't get their way in one vote or another. But do I see people ever say that they have left their countries? Pretty much never.
We're too busy whining about domestic politics in the new one and talking about how we're going to leave it :).
