Robert Griffin III is firing back at the racist haters attacking LeBron James' son, Bronny, for taking a white classmate to prom ... saying, "LEAVE THESE KIDS ALONE!!!"
That's right -- grown ass people are mad about who a 17-year-old kid took to a dance.
Here's the deal -- LeBron's wife, Savannah, shared shots of Bronny's big day to social media on Wednesday ... showing the junior hooper and his date, a senior student at Sierra Canyon, all dressed up for the event.
