Only 21% and 12% are against in Sweden and Finland, respectively, vs 57% and 76% who want to join. I understand your point about fracturing politics on issues like this (we're still paying for "Brexit"), and that 10-20% is a fair chunk of voters, but even then, you've got to be really against it to throw your lot in with an extreme single-policy party. A minority of the minority will be disillusioned or angry about it. Given that the vast balance of opinion wants to join, joining takes months and can be reversed, and both countries have general elections within the next 12 months, I think democracy will be just fine.
