As far as I can tell, the people who were most likely to vote leave are those that are least affected by the EU. The older the voter, the more likely to vote leave. What they did was take advantage of all the benefits the UK had from being part of the EU, and then say "fuck it, we don't need that stability anymore".
A good friend of mine got a message from his father along the lines of "sure, it'll be chaotic, but it'll work out in the end". The response was along of the lines of "well done, you've just injected a huge amount of uncertainty and instability for your children and grandchildren, and for what?"
The difference in reactions is also notable. I (and others) were looking forward to getting this whole debacle behind us. We weren't going to be happy if Remain one, we were going to be relieved. On the other hand, I've heard "Independence Day, gentlemen", and "it'll be fine, everything will recover, and it good because we'll get back control".
I know I'm biased, but I've seen a disturbing correlation between the people who are stupid enough to install ransomware, and people who think the outcome is great. It's basically the people who have no concept of consequences.
