I get why, it's been very divisive. I've learned when not online to keep my opinions to myself. I think that's why it came as such a shock to people when leave did win but for those who sat quietly and waited their turn at the ballot box, it wasn't a huge surprise. I live in arguably (because I've read about 4 or 5 different areas that claimed it) the area that voted the highest for remain, and honestly the backlash afterwards has changed my opinion to a certain extent of where I live.
For me, I know that the UK had it good within the EU. I know that we had opt outs, I approve of many of its values but ultimately I don't see it having a successful future, and I still believe that. Economically, I think the Euro is a disaster, and it will unravel in the next 10-20 years and in turn will bring down the whole project. The EU feels very unbalanced, and unless they agree to full fiscal union it will never work.
Tiny point, and although I still would have voted leave, one of my children was in a class with the child of our MEP their whole school life, 5-16. If ever you needed an advertisement for the stereotypical bloated MEP, it was them. Before I even knew who they were my opinion had been formed just by their behaviour. Entitled, arrogant, virtue-signalling, hypocritical, condescending champagne socialist. Showed themselves up at events and I have anecdotes of poor moral behaviour. Completely depressing that they were the representative for my area and had their equally awful partner on the payroll too.
