The teacher should have kept such opinions quiet & taught strictly the history and symbolism of the flag. Shouldn’t have thrown in commentary about white peoples who value it, either.
I’m sure was a racial slur used to describe black students who revere a particular individual or symbol all of Hell would have broken loose.
And no, I think valuing that flag in this day and age is not only remaining stuck in a time warp, but not caring that one is associated with a symbol that for many symbolizes racism and enslavement.
Just teach the freaking class and leave personalized insults out of it already. Glad whoever it was is on leave.
