You missed your chance then - treaties already require member countries to defer to European rules where conflicting.
My country has a supreme law written in 1978. Any other law that conflicts with this one is illegal and must be repelled. Anyone who wants to overturn our 1978 law is effectively declaring war to us.
The first modification to that 1978 document came 14 years later, done for the sole purpose of keeping it in compliance with the Maastricht Treaty. The line in the sand you are fervently defending was crossed a long time ago.
I guess this is why geeks are largely not involved in political processes. People seeing all topics as 1s and 0s are called maximalists and typically laughed out of the room.
