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.
Bronny was decked out in a flashy blue and black suit ... and his transportation of choice was a custom-print Mercedes with a sporty spoiler, worth hundreds of thousands of dollars.
Pretty awesome, right??
Well, some disgusting haters took issue with Bronny's date not being black ... commenting some awful responses under Savannah's post -- even accusing the girl of being a gold digger.
Enter RG3, who defended the teenagers in a passionate tweet this week.
"LEAVE THESE KIDS ALONE!" Griffin -- who is married to Estonian athlete Grete Sadeiko -- said on Wednesday.
"People clowning Bronny for his prom date are just miserable. Let them enjoy their day."
RG3 followed up with a passionate video ... saying the hate is giving off creepy energy.
Griffin has previously shut down his own criticism for not marrying a black woman ... saying, "It is not anti-black to love someone outside your race."
LeBron has not spoken out on the backlash ... but commented on his daughter Zhuri's expression in one of the pics that has since gone viral, saying, "Zhuri ain't f'n around! She don't play about her brothers!! 🤣🤣🤣🤣🤣🤣🤣."
