You're making assumptions on what Swedes believe and how much power they have. A lot of Swedes do care based on the ones I've talked to. It's the politicians that don't care and are making decisions for them. Sure, you can vote them out in theory, but if 51% vote for a pro immigrant party and 49% vote for an anti-immigrant party then that means 49% of Swedes are left disenfranchised. Especially, if a portion of the 51% are recent immigrants and are more likely to vote for a pro immigrant party.
