Why are Morrocans and Koreans not welcome in the Netherlands?

The Netherlands is a very a racist country, l but they're known especially for their hatred towards Morrocans and Koreans. I saw a video of a young Korean boy getting harassed by a group of grown Dutch people. Morrocans can't even walk the streets of Holland as they're easily hunted down and sold on the Dutch black market. What the hell is wrong with this country? And why do they hate Morrocans and Koreans?
