Thing is, ask enough people and you'll get all sorts of anomalies regarding that sort of thing. I'm now 60, and I know of several people who voted leave, every single one of them under 40. several with degrees, and one a company director. Hardly uneducated, but possibly atypical due to the vagaries of chance regarding whom I happen to know.
I, with a postal vote, and NOT following the news bar once in a blue moon, voted in blissful ignorance of the nature of the public debate on the matter, and did so (stupidly) in momentary annoyance at some remarks of a German politician. My concern regarding the EU was that all that politicians seemed to think about when it came to the matter of immigration was the economic impact. Not one seemed to be thinking about the social impact of parts of countries experiencing relatively swift influxes of poorly-integrated non-natives. When the cultures of those non-natives are too different to the local one, friction ensues (and please note, I'm not simply talking about what are generally (and incorrectly) seen as faith-based cultural differences).
I think the EU is a great idea that's been poorly implemented. I don't give a damn what country someone was born in, or what colour or faith they are, so long as they respect local laws and society. In particular, that they respect womens position in law in the UK - that we are not chattels and do not have to do what men tell us to, that we are free to marry whom we please and dress as we please here. Also that being gay isn't a crime in this country
I'd hazard a guess that the majority of immigrants to the UK get that. But some do not, and it's disturbing when one encounters women who've lived here for many years who can barely put a sentence together in English, or women who've run away from their families to escape an arranged marriage. It's damned annoying to experience being spoken to as if a whore by a guy of Asian descent because I had bare arms and an uncovered head one summer (and I overheat easily!), and a few months later have an eastern European guy angrily demand to know why I was wearing a headscarf (because it's freezing cold and I get migraine if my ears get too cold, prick!) - as to him, any woman covering her hair must be Muslim (which in his mind is only ever bad thing. Cretin!).
So my anger at untrammeled immigration was that there hasn't been sufficient effort - with associated costs - in ensuring that immigrants to the UK understand the native culture, respect it, and are willing to adhere to its laws and social norms. So no harassing women in the street for not adhering t some other cultures norms, no arranged marriages unless those to be married BOTH agree of their own free will, and CERTAINLY no female genital mutilation (nor male come to that), and if you don't like gay men and women, that's fine, just don't harass them and don't have sex with them, that's all.
The various Governments for decades haven't put enough effort into integrating immigrants, and companies typically don't give a damn about social issues so long as the labour is cheap. Well, IMO companies should be made to pay the social costs of the untrammeled migration that is so economically good for them..
Part of the problem, of course, is the sociopathic notion that people exist for the benefit of companies, when it ought to be the other way around. But that's a whole 'nother argument.
Anyway, so yes, with my postal vote, in a moment of anger and blissfully unaware of the public screaming-match that was going on on the subject, I voted to leave the EU, never imagining either that
(a) the leave vote would get anywhere near winning or that
(b) David Cameron was stupid enough to hold such a referendum without an already thought-out plan to deal with either of the possible outcomes or that
(c) if the purely advisory referendum resulted in a Leave victory, that the collectively dunderheaded Tories would then treat the thing as if it were legally binding and carved on stone like divine writ. And those young pro-Brexit voters I spoke of - felt pretty much the same as me, it turned out, when I spoke to them, and included amongst them people of widely varying ethnicities, countries and cultures of origin. In short, some of them were immigrants who appreciated our laws and culture and were as concerned about those who do not as I was and am.
Now, personally, when, about a week before the main vote took place, I became aware of the way the public discussion was being mishandled, I was apalled. I don't think I've ever encountered such cheerfully dishonest and abusive political campaigning on either side. But folk I spoke to, whether in favour of leaving or not, seemed generally rational and could make good arguments for their stances., it's just that their perceptions of what were the problems and plusses of the EU and how fixable the problems might be varied.
Yes, both side had lunatic fringes - that's a staple of all political campaigns. But to have a Government behave so ill-advisedly on the unexpected result that they were not prepared for of a non-binding referendum?! And to carry on doing so despite the clear stupidity of doing so and evidence of foreign interference in the pre-referendum campaign, no less!?
One thing Remainers have absolutely right - you can't change the system if you're not in it. The referendum result should've been a signal to HM Govt - and their counterparts in Europe - that there needed to be serious consultations with the populace of Europe, NOT the companies operating therein (who get way too much attention from politicians anyway), of what aspects of the way the EU is run that they did not like - and then serious consideration of how best to tackle those problems, followed by pragmatic action thereon based on the realities of the world rather than on anyones Utopian dreams.
Then again, maybe expecting politicians to behave rationally and in the interest of the populace they are supposed to represent is MY Utopian dream... sigh...
