I have mixed opinions on this.
White (my own) perspective
She's not saying anything worse than what whites say around each other when no other minorities are around. We even say it about each other and about other lower class whites. Shit, white people have said it about myself at various times throughout my life as I certainly wasn't from an upper class family.
They might not word things exactly as she said it, but a lot of whites will say very similar things when they're around a comfortable group of fellow white friends.
And yeah, even the liberal parts of my family are getting sick of the "white privilege" crap that's being thrown around. Like I said, she didn't say anything that we don't already say amongst ourselves.
However, most of us know when not to cross that line in public and use common sense. This is coming from someone who has lived in Trump country my whole life, when the Trump/Pence signs were in full display in the yards throughout the town before Trump even started building up a lot of steam in the primaries.
As a white parent, while I wouldn't feel like my (hypothetical white) kid was under attack in this situation, I still wouldn't want someone who openly and brazenly went on a podcast and stated these views to be in a position of authority over my child.
Minority (not my own) perspective
Looking at this from a minority view, which obviously is difficult for me to do, but I would be freaked out if a person who was in a position of power said these things in a very open manner like she did when she was my child's teacher. She was going on podcasts and shit, that's pretty out in the open.
I would not to be happy with the school system and I would quite frankly be pissed off that this teacher was allowed to be in a position of authority around my child.
I would very much think that my (hypothetical minority) child would be under attack if this ever happened to me.
Now all hypothetical scenarios aside of whether my white or minority child was under the supervision of this teacher, I would also like to add something that maybe other minorities on this forum might not think about.
This is, simply put, that many white parents are feeling as under attack on a regular basis from academia and the public school system that minority parents probably felt in this circumstance. How so? Well, let me give you an example:
How does it make white parents feel when their kids teachers are part of Black Lives Matter, a group which openly and proudly chanted "Pigs in a blanket, fry em like bacon" while holding up the black power fists?
Not only will that teacher, who is part of Black Lives Matter, not have each and every future job opportunity taken away from them, but they will be actively celebrated for being "courageous".
Lets not pretend this is a one way street.
