My mum voted Brexit because she doesn't like the Germans (she was a child during WW2). In her mind, that emotion trumps any argument that many of her grandchildren , nephews, nieces etc work in the supply side for the foreign owned car industry, and their jobs could be under threat. She has a "this was their finest hour - we will never surrender" view of British exceptionalism and repeats "I think we will be alright" to my arguments about brexit downsides.
Religion is regarded by the common people as true, by the wise as false, and by the rulers as useful. — Edward Gibbon
