"Critical race theory in its most fundamental way is not being taught K-12," said Dr. Deborah Stroman, a UNC professor who focuses on racial equity. "I would say that we all need to breathe. And think about the why. If you have a group of people, a collective who have been underserved, been in harm's way, who have been oppressed, who when you look at the outcomes in all of our systems are not doing that well, why would we want white people to feel guilt. Why would we want people to be white people to be fearful, why would we want people to go in white people to go into a shame mentality, that makes no sense."
