I think your example is not a good one. Nordic countries have the concept of Jante law. If you can verbalize such a concept and also recognize that it exists in your society, by definition it makes your society more intolerant than a culture that has no such concept (such as the USA).
In fact, I would argue the open-ness and tolerance of nordic culture is specifically exploitative of the cultural expectation that you do not raise concern or object and are expected to be in agreeance with everyone else that "this here is a tolerant society". It's a valid theory that the fastest culture to adopt any philosophy will be the one that has the population with the greatest number of people who don't disagree.
