It's not about a specific country, its about the act itself. Besides most swedes aren't even proper christians. Even if they do allow it the quran is sacred to us and it would be dishonest to claim burning it outside a mosque on eid isn't an islamophobic and hateful act as well as a provocation.Sweden is fine with with bible burning too: https://www.ynetnews.com/article/rji7uqrfn
They are not targeting Muslims, it's an exercise of free speech and whatnot, you're allowed to burn books.
