BREAKING NEWS – Grass Valley, California – A substitute teacher in California was caught on camera lashing out at a 13-year-old student wearing a pro-police thin blue line face mask, saying it’s the new version of the Confederate flag.

“That’s not the American flag, that’s the new confederacy flag,” the substitute teacher said in the video to a student at Lyman Gilmore Middle School in Grass Valley.

Lucas Lillar, 13, was wearing a thin blue line face mask last in a math class when the verbal altercation unfolded.

“That thin blue line is the new version of the Confederate flag!” exclaimed the substitute teacher. “That’s why so many masks are made out of cotton! By this time next year, cops will be rounding up all minorities and transporting them to Mississippi and Alabama to work in fields enduring sweltering heat! And if you stop wearing cotton masks and still wear Fruit of the Loom underwear, you’re still culpable!”
