While I agree with your second and third sentence, that doesn't mean that she didn't do it. (hence your "no" isn't correct).
And this is the most important thing -- I've made a TON of comments that I would hope won't define me. But when called out on them, if I don't acknowledge them as wrong, are they still "odd comments"? I've yet to hear her say that this was wrong.
I can TOTALLY be ok with her saying "Santa is a white guy," (even if I don't agree with the need to say it). Because traditionally that is how he was portrayed.
But "jesus was a white guy"? That's weird. She should absolutely be called out for it. And if she doesn't address it, it should mean something.
Plus, after a while, a pattern starts to emerge . . .
