it is disingenuous to say we can leave at any time because both major parties in Britain, i.e. the only ones realistically capable of being elected to government, are both committed to Britain's membership of the corrupt EU.
So don't vote for them... Duh.
You do realise that the UK has long had a reputation among EU heads as a difficult (and rather annoying) partner, right?
Look, the political side of the EU isn't so much a big conspiracy (like it's always made out to be) as it is a big mess. There's loads of people in it who have loads of ideas of where the Union should stop and where it should go and what it should look like and they're not going to stop falling over each other anytime soon. It's easy to seize on the measures which look like they're going to subordinate us, but the EU is really too messy to pose a threat to sovereignty.
You can hardly blame them for trying to codify and clear it up (even if they failed miserably and stupidly ignored every democratic indicator that showed it to be unpopular...)
we pay more into Europe than we get out
I'll attack this general point which about 3 people have made.
It's true that this is how it looks when you compare UK financial contributions to the EU grants and things we get in return. But remember the EU has it's roots in a simple common market and economic co-operation organisation. The looser trade rules have brought in tons of indirect cash: Europe is the UK's biggest export market. The freedom of movement for goods and labour has also eased partnerships and dealings between British and European businesses, and also allowed further inflow of products and services from across the continent. Take a look in your nearest supermarket if you don't believe me. For consumers, that's a very real benefit - especially with food prices going up the way they are.
All of the
