Swimmer Riley Gaines blasted San Francisco State University for praising a “peaceful” protest where she alleges she was attacked by trans-activists after urging that transgender athletes be kept out of women’s sports.

Gaines, 23, threatened legal action against the school for its alleged failure to help her after droves of trans-rights protesters pushed back at Gaines’ controversial Thursday speech. …

Gaines claims she was punched twice by a transgender woman and was forced to barricade for hours in a classroom.

Following the mayhem, Jamillah Moore, vice president for Student Affairs & Enrollment Management, emailed students thanking them for taking part in the event.
