As others have said, the idea that "all real decisions are made in Brussels by non elected representatives" is not true.
In the UK, around 5% of our laws (at present) are EU laws. These mainly cover areas of trade, human rights, etc. The other 95% are purely the responsibility of Britain and our politicians here, similar to in France (although not completely the same as we do have some additional devolved powers in Britain).
Even then, the EU parliament consists of elected politicians from all nations, that's why countries vote for MEPs (Member of the European Parliament). Finally, there are vetoes where countries can reject the implementation of legislation if they disagree with it.
I am simplifying things here a lot, but the idea that rules are forced onto countries without any control is not true. Also, the whole "unelected representatives in Brussels" is the line often trotted out by the anti-EU brigade, but it is simply not true.
