"Friends" co-star David Schwimmer wrote a blistering critique aimed at activists who ignore or question Hamas terrorists' sex crimes towards Israelis on Oct. 7.

Schwimmer, who is Jewish, wrote on Instagram Friday that he has been an advocate against sexual violence for nearly 30 years.

Referencing the New York Times' recent investigation of sexual assaults at the beginning of the Israel-Hamas war, Schwimmer emphasized the importance of believing survivors.

"There are incredible organizations and individuals that I count as allies in this work," he wrote. "Who for years have stood up and fought for survivors of rape and sexual assault, demanding justice — many of whom are survivors themselves. And yet…"

"For many of them, denying it even happened is a convenient way of avoiding compassion and personal responsibility," he wrote. "Perhaps this article will finally make them realize they got it wrong, and come to terms with their unconscious bias."

"Because — as they know better than most — their refusal to believe the survivors has RE-TRAUMATIZED them, as well as their families, friends, and those of us who did believe them," Schwimmer added.

The Instagram post was not the actor's first time commenting on the ongoing Israel-Hamas war. Earlier in December, Schwimmer called university presidents who failed to condemn antisemitism during hearings "morally bankrupt."

Actor David Schwimmer recently took to Instagram to criticize people who refuse to question Hamas' barbaric actions on Oct. 7.

"Incapable of answering even the most direct ‘yes' or ‘no’ questions, watch them duck and smirk at the unbridled anti-Semitism [sic] and calls for genocide on their campuses," Schwimmer said. "Where is the outrage among students, faculty and alumni demanding their resignations, an official apology and enforcement of the codes of conduct?"
