>You just claimed this, without any reasoning

Unlike nearly every other parliament the EU parliament cannot propose legislation. You may ignore it, but the reasoning for the claim was plainly stated.

>members of this parliament are freely elected and they can decide out on their own whim

MEPs are entitled to their opinions, it's just that they hardly matter. Everything voted on was already decided between the commission and lobbyists before behind closed doors.

>Also, "the EU cares about" is silly.

Many thousands of people are employed because of the EU parliament. It must exist for some reason or else it's just a colossal waste of money. Usually the point of citizens electing representatives that control their government is democracy. If instead those representatives have no power it is because the intent of the system is a potemkim village. An illusion of democracy, in short, a fake.

If anything the EU parliament is like the UK house of Lords except the British know the lords are pointless and continually try to abolish it.
