Denmark has a population of 6 million people with a homogeneous culture, ethnic composition (87% Danish descent, [0]) and physical location. Many problems are going to be faced to all Danes simultaneously.

It is much easier to construct a shared agreement on what is true in such an environment. That they are a democracy is less of an issue than the fact they all face a very similar environment and can probably agree with each other on what the truth is because they are all looking at the same thing.

There's no requirement to have a "homogeneous culture" or specific ethnic composition in order to have a working democracy. Facts are facts, and with a free press, can be seen by anybody, of any race or culture. The real problem is with authoritarian cultures (which are an aspect of humanity, not specific ethnicities) imposing themselves on ordinary people.
