OK, so the problem is that I find it basically impossible to understand how a well-informed and rational person could come to the conclusions you've come to.

The EU isn't perfect, but you'll struggle to argue that it hasn't expanded peace, prosperity and human rights across the continent. This is motherhood-and-apple-pie stuff.

Arguments in favour of Brexit thus tend to boil down to immigration and 'sovereignty'.

There's a consensus amongst economists that immigration makes us financially better off. That makes it hard not to ascribe a strong desire to cut immigration to a powerful desire for ethnic homogeneity and/or a powerful dislike of foreigners. Those things are very close to racism.

Meanwhile, the 'sovereignty' Brexit delivers is almost wholly illusory. In practice, we'll get to choose which of the big players to take the rules from. That's going to be either the US (which hardly anybody actually wants — most Brits value our health service, non-toxic food and drinking water, holiday pay, and so on — and also isn't very helpful, because the US is far away) or the EU (whose decisions we used to play an outsized role in, but no longer have any influence over).

It would be hilarious — if it weren't tragic and a little terrifying — that the ones in charge of 'taking back control' are also the ones stifling parliament, suppressing voting, and attacking academics, judges and the rule of law. As far as I can see, the only ones taking back control are the rulers, and the only ones they're taking back control from are the other citizens of the UK.
