The danger is that you avoid doing what’s necessary, and end up with a status quo that’s worse than the change you wanted to avoid. Currently deadlock, infighting, and division mean the EU is increasingly beholden to foreign powers. I mean, sure I’d prefer it if ‘my’ party had power in the EU. But I’d still prefer the ‘other’ EU party over China.

Also, judging by your comment, I assume you’re also from a country with a (defacto) two party system. But the EU is basically like a multi-party system. So the ‘other’ EU party, won’t be the polar opposite of ‘my’ party. It’ll be a coalition of parties, who have reached their own internal compromise, which means extremes are avoided. Multi-party systems are also usually less dramatic in their swings. Eg. the Netherlands where if Wilders leads a government, his more extreme positions will be tempered by his government coalition partners.
