Motivation for expats voting for Brexit

[Deadsouls]

I did post in the Brexit arms but no answers.

Briefly, here is the scenario.
My parents live in an EU country, emigrated over 15 years ago. There are quite a few expats in this area.

Last night I met a couple in the 60-65 age group who had recently retired here from the UK, having had a house here for several years. They emigrated here in April. They voted to leave the EU last year.

Now, I didn't yet get around to having a discussion with this guy. But....I am curious as to possible reasons/motivation for voting Brexit...
They said they love the life here.

1. Immigration - they are immigrants are they not? Into a country that has quite high migration.

1. Sovereignty - they have left the U.K. to live in a country that remains a member of the EU. Therefore will remain living under EU law/legislation.

1. For the people remaining in the U.K., as in living and working there? Why not stay in the UK to take advantage of the projected benefits of Brexit?

They will at this point be benefiting from reciprocal healthcare and so on, how this will change, not sure.
Hmmm I feel I am missing something. if you voted Brexit to not be a part of Europe (law/economy etc), why move to mainland Europe? I don't understand it. Can anyone explain?

It makes no sense to me at all. All the expats I know, which is quite a few being one myself, voted remain and are extremely angry about the result. I don't know if it makes a difference that they are all work migrants rather than retirees.

Well Turkeys do vote for Christmas. Brexit is a really good example of that whatever the reasons given.
