Cal Poly don't play when it comes to hate speech -- the University just REVOKED a scholarship for a star high school wrestler who was caught on camera using a homophobic slur while holding a Donald Trump campaign sign.
The wrestling star is 18-year-old Bronson Harmon -- who scored a medal in the California CIF State finals and earned himself a scholarship to Cal Poly San Luis Obispo.
But now he's more famous for a 31-second video -- featuring Bronson and his father protesting at a Keep Families Together rally in Modesto on June 30.
Bronson was holding a Trump 2016 sign -- when he walked by immigrant rights protesters ... turned to a camera and yelled, "Fuck you f****t."
Another man -- reportedly Bronson's father -- screams, "Send their asses back."
Bronson allegedly shoved a man into a tree during that same protest.
The video was posted on social media and went viral -- eventually Cal Poly saw the clip and revoked his scholarship.
