Excellent post railman. I've had to do a lot of digging to find good sources of information, but I found that when I searched for information about one subject I would often find links to other interesting stuff. Honestly I believe the only way you can decide how to vote is by reading things for yourself and if you're lucky, discuss things with other people. I wish I could discuss the referendum with my late Dad. He was a sponge when it comes to information and all my family loves a good discussion (we're never short of opinions
). Sadly we're spread all over the place these days, so that's not an option for me. Good luck. 
Gagagran I agree the electorate was never given the opportunity to vote directly on the changes brought in by the Maastricht Treaty. We might even be the only country not to get a referendum, I can't remember.
However, the Tories were in power from 1979 until 1997, so if anyone voted Tory at the general elections, then by default they did vote for the Single European Act signed by Margaret Thatcher in 1987 and the Maastricht Treaty signed by John Major in 1992. Even after the Maastricht Treaty was signed, closer ties with Europe was a Tory 1992 election manifesto promise.
The Maastricht Treaty was a success both for Britain and for the rest of Europe. British proposals helped to shape the key provisions of the Treaty including those strengthening the enforcement of Community law defence, subsidiarity and law and order. But Britain refused to accept the damaging Social Chapter proposed by other Europeans, and it was excluded from the Maastricht treaty.
It's worth mentioning that Labour's 1983 general election manifesto (when the party leader was Michael Foot) pledged to begin negotiations to withdraw from the EU "within the lifetime" of the following Parliament. But of course, Labour lost the election.
And we do have a say and in several ways. Firstly we elect our MEPs and secondly we elect our MPs. But more importantly the UK government negotiates every change within the EU.
That said, when the impact of any new regulation is scrutinised by the Regulatory Policy Committee, all though initially it considers the impact on a wide scale including consumers and the public service, when it comes to the final risk impact assessment, the new regulation can only regarded as not fit for purpose if there are concerns about the estimated cost to business. Nothing else and it has been criticised by the OECD for this approach.
It's up to the individual how much interest they take in our government, but we can't blame everything we don't like on the EU. How a policy is implemented is down to our government and our local authorities, etc. right here at home.
