I don't know, is it worse when the racism exists but no one acknowledges it or gives a voice to its victims? Or when racism is at the forefront of society at all times, but those impacted by it have their voices more readily heard and have more of an impact in the society overall?
I legitimately can't answer that, but I do know that racism is equally prevalent and serious in virtually every country on this earth. Some places are just more honest about it (or rather, unable to obfuscate or hide it).
None of that negates the progress of most Nordic countries though. Their reforms and societies SHOULD be looked at aspirationally, because they produce better outcomes. The challenge is in achieving those same reforms in places that are less homogenous.
