The EU is one entity, consisting of several member states. Just like my own country consists of many regions and municipalities with their own elected officials.

Member states are forced to comply with legislation passed by the EU, even if a majority of the citizens of a state do not want to implement it. Technically there are two other options - sufferimg massive fines and punitive actions by the EU, or leaving. I’d rather not have to endure either of those, so instead I complain, loudly, online, to politicians, MPs and MEPs.
