UK MEPs have only ever voted _against_ 2% of laws introduced by the EU (laws about human rights and closing corporate tax loopholes), they have voted _with_ 95% of the time. There's a reason for this, they took part in the shaping of those laws.
Now we have no way of shaping laws throughout the continent we're a part of. We've thrown it all out the window because someone told you that the EU is trying to stop us from having bendy bananas.
