I think you misunderstand me. I didn't say you personally lost any freedoms, but your nation as whole HAS. They are giving up their freedom to regulate some of their own practices, such as agriculture, finance, and possibly (I believe that this has not been finalized for the EU yet)even foreign policy. How do you feel that submitting to the EU's authority on these things is NOT a loss of freedom? Just because you permit it doesn't mean it's not a loss, kwim?
I wasn't speaking of defense, by the way. I was speaking of your foreign policy objectives. Your government already goes in different directions from both France and Germany, for example. From what I can tell, the UK's foreign policy is much closer to that of the former Soviet Republics and Australia than any other country on the Continent. Going along with a Foreign Minister from another country might be hunky dory when you agree, but what happens when you don't? All of this power is being centralized in areas that are not always going to be friendly to the UK's interests. The effects of this can trickle down to you, as well.
