I’m old enough to remember when Rachel was just a nobody too. Now she feels entitled to some ESPN show or something because of her veteran status. Is she guilty of racism or simple divaism?

Right on. If ESPN doesn't fire her they're essentially confirming that Maria was a diversity hire and nobody said/did anything wrong. That's the only way to interpret it. You can't throw your employer under the bus like that and just sail on. It sure looks like a bad time out there.

Even Adam Silver is saying "too little too late."
It just proves how replaceable all those people really are and 99% of it is who you know who you blow.
