Racial quotas are racist in general. But, this racial quota is especially reprehensible.
The non-Hispanic white population is over 60%. The white-Hispanic population is about 9%
So, depending upon whether they treat white-Hispanics as POC or not, they are capping the representation of about 60% or 70% of the population at 50%.
This would be like making a rule that no more than 10% of players in a season could be black, when black Americans are about 12% of the population.
If they capped non-Hispanic whites at about 60% it would still be wrong, but at least they would be trying to match the demographics of the American population. Under this policy, they are deliberately discriminating, based upon race, to achieve a mix that is far different than the demographics of the American population.
What makes it worse, is that the "problem" they are trying to address no longer exists. They has reached a white/non-white distribution that approximated that if the American population, in recent seasons.
I would have absolutely no problem with seasons with 50%, 60% or 80% "POC", as long as they got there by picking the best contestants. But, racial discrimination is ugly and even when it "favors" minorities, I believe it harms them more than it harms white people.
It declares that the most important thing about minorities is their race. This marginalizes them. There is also the evil implication that they must not good enough to make it on their own, so they need discrimination to help them.
BTW, I despise the racist, woke hypocrisy of the term "people of color". It is an absolute synonym to "colored people", which was deemed a slur about 50 years ago.
It is just an example of our modern, woke racial insanity. Just treat all people equally. That is the Only way to end what is left of racism. Instead, the woke mob has created an ugly revival of the racism that was nearly dead 10 or 15 years ago. This is a tragedy.
