There is nothing wrong with individuals of different ethnicity mixing, having offspring, etc.; or even with a private company promoting it if they choose to promote these kinds of politics (unwise business decision, in my opinion). However, seeing this come from a state-owned news organization--in this case The Crown, who owns the CBC--and pushing propaganda like this is disturbing. Especially since another news organization owned by The Crown reported on a scientific forecast that humanity will split into 'two sub-species' beginning in the year 3000. A claim directly referenced in this rap song! Video starting at 'year 3000' timestamp

Evolutionary theorist Oliver Curry of the London School of Economics expects a genetic upper class and a dim-witted underclass to emerge.

The human race would peak in the year 3000, he said - before a decline due to dependence on technology.

People would become choosier about their sexual partners, causing humanity to divide into sub-species, he added.

The descendants of the genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative and a far cry from the "underclass" humans who would have evolved into dim-witted, ugly, squat goblin-like creatures.

My post isn't to suggest multicultural interbreeding itself would be the cause for the creation of a dim-witted, ugly, squat goblin-like sub-species. But the promotion of this propaganda appears to be pushing for such an outcome.

As you're probably aware, the British Royals have a historical habit of maintaining their genetic 'purity' through familial inbreeding (Wikipedia). It reeks of Nazi ideas of a 'master race', which is why I called the propaganda racist.
