The EU Parliament, who we vote for every 5 years (and have elections coming up), vote for a law. You don't like said law, therefore it's undemocratic?
The way the parliament is elected is quite fair - it gives a little more power to people in smaller countries, but that's not unusual (UK westminster constituencies vary from 22k to 120k. U.S. congress areas are more even, ranging from 500k to 1 million). There's an argument that it should be more even than the current 11:1 ratio, but we call the U.S. senate democratic and that's a 69:1 ratio.
The actual choice of MEP comes down to a proportionate election, meaning that if you get 15% of the votes, you get 15% of the MEPs. This beats fptp systems where MPs in the house of commons are elected with as few as 30% of the votes cast.
Voting for a representative is the very essence of representative democracy. Perhaps we should have direct democracy. As it happens I watched an episode of The Orville[0] last night which covered this scenario.
Personally I'm a fan of representative democracy. It's the worst system except for all the others. I expect my representitive to work full time in understanding proposals and voting on my behalf, but they are a representitive, not a delegate. This is where direct PR falls down (who gets the seats is down to the party, not to the voter. I can't vote for Candidate B rather than candidate A if they are part of the same party. STV works better in this case, although 90% of voters don't really care and in the UK 80% don't even know who their MP is!
