It is, but under DPRK terms.

There's a quote saying: There are "not two but three Koreas: North, South and the American military bases.

But I get what you mean, and that's why the DPRK have been the ones pushing for a reunification, because there should be only one.

It's more an abscence of a law. There are several mentions in documentaries, books and even some Western news about how employers can deny the job to a candidate only based on lack of attractiveness... and we are not talking only about models.

I think Baroque, Classical and Romantic music were composed mostly by brilliant people unfortunately living under nobility and Imperial regimes, but refusing to admire these masterpieces only because how they were made is akin to people banning Tchaikovsky just because he was Russian.

Though be careful with Wagner and people like him, I'm not well versed in that period and he was mostly sure a white supremacist based on his influences.
