Caitlyn Jenner had her ass handed to her by an angry trans activist at a Tran Chorus of L.A. performance of The Rise and Fall of Ziggy Stardust and the Spiders from Mars Saturday night.

At the event — made possible by Jenner's bucks — Ashlee Marie Preston got right up in Caitlyn's face over her support of Donald Trump ...

As reported by the Los Angeles Blade's Troy Masters, Ashlee told a gobsmacked Caitlyn:

It’s really fucked up that you are here. Some people may be afraid to confront you for being here, but I am not. You are directly responsible for what has happened with transgender soldiers and the military. I am not afraid to say it to you, I am not. I am not afraid.

Jenner idiotically replies that Preston does not know her. What?! We all know Caitlyn Jenner — intimately — thanks to a four-plus decades in the public eye, multiple reality shows, books, magazine articles and her very articulate way of expressing her beliefs and opinions.

We know you, Caitlyn, and we have your number. No one more so than Ashlee:
