Quotas are legal in many states. Granted the author is likely based in CA. Still, let's keep away from absolutes.
FWIW I also don't support discrimination in whichever direction. However, so far the story is "there was some kind of

Not to mention it's a crime.
Similarly to why it's bad to assassinate an employee. It's not because of performance...
