I can't comment on the discrimination suit, but I CAN comment on her aptitude. My daughter was/is in her science class, and it was a sad joke.  My wife and I constantly asked each other, "how can this person still have a job and not have gotten fired yet"? She is grossly incompetent to a degree that would be funny if our kids' education wasn't at stake.  I have severe doubts that any sanctions against Ms Holloway are discriminatory, given her extreme incompetence.
