I'm not going to start posting in this thread a lot as tbh I don't really want to talk about this subject but, ....talking percentages is a little misleading imo.
From what I've read:
Thursdays referendum saw 17.4 million (51.9%) votes cast to leave the EU, compared with 16.1 million (48.1%) for remaining with a turnout of 72.2%.
That equates to a difference of 1.3 million people who voted to leave the EU, ...that's hardly a small difference imo. Basically the population of a small country voting the other way (population of Estonia or Trinidad & Tobago for example).
It's happened now so people just need to get on & look to the future to see what happens next.
