My reasoning is that the people who voted for Brexit had something they wanted in mind but won't say what it is. Whatever it is. Whether it was for trade, or healthcare, or to figure out what their national culture is. Either way, they'll get it. That's why they don't regret it.
They're probably still celebrating getting one over the "metropolitan elites". Seems like the vote gave them the catharsis they wanted.
Many people voted for Brexit as a protest vote, and I hope it was worth it for them. I hope people were satisfied with Cameron's resignation (I personally saw him as a rat jumping a sinking ship; he agreed to the stupid referendum).
I personally don't believe in collective regret. There's no such thing, especially in politics.
