Ok, first I'm not totally against EU and I know they did some good things, but heres some things from the top of my mind that relate to my personal liberties:
- Barroso being elected in a secret vote by EU parliament (I'm sorry, but that isn't very democratic)
- Circumventing Ireland's vote on the the Lisbon treaty, but saying in the EU parliament that even without Ireland's vote, they will modify whatever in the rules is needed for the Lisbon treaty to come into effect (Think it was Barroso and some Belgium guy that said that)
- Trying to ban sale (not sure what was the resolution on that one but was supposed to come into effect early this year) on all over the counter supplements.
- Forcing US vendors to setup a local presence to pay VAT on online shopping (even of digital goods).
- While this was was sorta deserved, since we did take their 'bailout' but Germany/France and now the EU saying countries should lose their part of their sovereign powers if they request help.
- Preventing, by direct influencing politicians, referendums in countries where a vote against some resolution is against EU ideas (leaving the Euro, leaving EU, signing the Lisbon treaty which by the polls some other countries pepole would also be against it) removing from the people the right to choose democratically.
The problems I see with EU was when they tried to shift it from a set of 'gentlemen' agreements about trade and free pass to trying to make it a full state (ala USA) without allowing the people to vote on whether they want to or not.
Edit:
While I can't find an unedited video, here is a good example why more and more I'm starting to hate the EU. Please do watch it and than explain to me that there are no liberties being lost:
