Re: You are confusing EU with Europe
If the reason for the departure of the UK was due to actual EU policies, that would have some relevance.
BoJo, and others from the Murdoch/Barclay press (let's be fair), have spent the last 20-30 years publishing outright lies about the EU though. Various anti-EU Conservatives have repeated those. Not too unreasonably, a lot of people think those lies are true because they're published in national newspapers.
As for a "better EU", it's important to remember that the EU, in its autocratic style, had the indignity to impose equal rights for older people, equal rights for gay people, equal rights for non-white people, equal rights for non-Christian people, equal rights for Christian people (in NI), equal rights for men to parental responsibility, equal rights for men to parental leave, equal rights for women pensioners, a national minimum wage... and I think I'll stop there. As those radical concepts (if you can describe "treat people properly" as that) were introduced, every Conservative party in government or opposition attempted to derail every single one. Several were opposed by the Blair/Brown governments too. The EU imposed them on the country, in direct opposition from the UK governments, because the EU considered them to be the correct thing to do. So which of those do you think shouldn't have happened? Which of those groups do you think should not have human rights?
Holocaust Remembrance Day was the other week, and one of the key peints was that people should learn how to prevent it happening again. The EU is, directly, a force to stop that happening again, because "other countries should not meddle in our internal affairs" leads *directly* to Kristallnacht, ghettos and gas chambers. It really is that simple - and the horrific part is that it's already started.
