Any they do have is political power

YES THAT'S WHY IT'S INSANE FOR COMMUNISTS TO BE DEFENDING IT LIKE THIS.

If it shoots down the budget a pro-eu government will always respect that decision because the pro-eu population (which is the majority in EVERY EU country) will agree with that, and if they don't they'll blame the EU and not their governments, so it's always a useful scapegoat.

Political power matters and that "any power" is doing a lot, you haven't dealt with this people, the EU is the chief obstacle for there to be a working class political movement in europe, and defending it because you're an "antifascist" is insane.
