I question it like I would any Pole who claimed to prefer Soviet rule over simple home run democracy. I question anyone that prefers to remain in the EU rather than have a more accountable democratic process over a super state. I think it is unpatriotic to want 60% of all laws coming from overseas.

If anything is made more difficult for your brother then that is down to the EU itself. To work or function overseas all you would need to do is apply and submit appropriate paperwork if the EU plays fair. It is easily done. In most countries a simple background check and a few supporting documents. Seems fair enough.

I think there is a lot of exaggeration too. Though there will be some issues, especially if May keeps pushing her nonsense deal, a no deal Brexit is the best thing for the UK IMO. Think long term rather than short term. There will always be a short term impact. It is for the best. Don't doubt yourselves.

Democracy is all people want. I doubt anybody wants a new empire. The empire building is the EU itself!
