No one in my social circle is pro-Brexit. The closest I get to pro-Brexit people are the people on a motorcycle forum I frequent. I have interacted with people there, and our positions are in fact quite opposed on the topics you mention.
On our values:
- London: I love London, whereas the pro-Brexiters generally see London as a filth-infested pit of crime, stabbings, Islamic terrorism, a failed experiment of multi-culturalism, and a grand distraction that occupies far too much public attention.
- Immigration: I distinguish between EU free movement and immigration, they do not. They do not value the right to settle anywhere you like in the EU in the same way I do. They see a feeling of European identity above national identity as stark raving bonkers, loony bin stuff.
- Nationalism: I've seen the poison of nationalism in Ireland and how it leads to conflict and violence; they seem to see little difference between nationalism and patriotism or supporting a football team. They don't understand the danger.
- Regulation: I am strongly in favour of central regulation for everything that affects inter-state commerce because the alternative is a race to the bottom with short-sighted politicians pursuing beggar-thy-neighbour policies. Whereas Brexiteers dislike regulations coming from Brussels, seeing it as an imposition with not enough democratic checks and balances. I'm sympathetic to the criticism of lack of democratic checks, but I think the answer is EU reform, not leaving the EU. Other, more left-leaning people might resent EU restrictions on state aid, I'm not in favour of state aid either - you see how US states competed with one another with tax breaks for Amazon, it's far better to have central restrictions on this nonsense to cut it out.
So on the topics you list, my position and pro-Brexit positions are opposed.
