"Research shows that... those that have quotas like them, and those that do not, fear them".

What utter nonsense.

That sentence is trying to pretend the following:

1. When people oppose quotas, it stems from an emotional fear of quotas.
2. Whenever quotas are implemented by new laws, people lose their emotional fear of quotas and subsequently they like quotas.

Who on Earth is the writer trying to kid?

Plenty of people oppose quotas for reasons that have nothing to do with fear, but rather have to do with viewpoints of fairness and ethics and justice.

And you can bet that in places where quotas were implemented by new laws, plenty of people remained opposed to them for the reasons (not emotions!) mentioned in my previous sentence. Which is to say that people are diverse, already! People are not little emotional cartoon stereotypes.

It is bizarre that a piece proclaiming itself to champion diversity is so blind to diversity in its own stated words...
