Why are people obsessed with the UK leaving the EU?

You can yse from some of the answers here, that the most of those that won't out of the EU, live in a world of nationalistic romantic grandeur. Basically a bunch of half wit football hooligans with no understanding of commerce or democracy. All talk about the hard earned money that the British have to pay, like other members to the EU, to the EU budget. Not giving any thought to where they earn that money, namely in the EU. Further more since our membership, millions and millions of pound have been invested by mainland European companies in the UK. Bring new jobs,technologies and opportunities. Of cause it's obvious that those that won't the UK out of the EU are not enjoying and are unable to reap the befits of our membership. So that's why they belle ache, even if there was no EU they would fine something else the bell ache about. They just have a constant pain in the A R S E about everything.But you seem to have the brains and attitude to understand that as a nation we can no longer stand alone, not even African tribesmen fear Britain any-more. To stand strong we must stand together.
