In a surprisingly open-minded move, the New York Public Library agreed to host an event featuring a handful of “canceled” feminists who believe both in women’s equality and in the scientific truth of biological sex.

Then, a week before the event was scheduled to take place, the “Evening with Canceled Women” was canceled .

“That’s right,” organizer Natasha Chart tweeted . “They cancelled us.”

Chart, the board chairwoman of the Women’s Liberation Front, was to be joined by five other feminist women, all of whom have experienced pushback for their belief in biological sex. One of the women, writer Meghan Murphy, has even been banned from Twitter .

Now, it seems like they’re all being blacklisted again. The NYPL never explained why it canceled the event, according to Chart.

“Dominique Christina, Libby Emmons, Linda Bellos, Meghan Murphy, Posie Parker, and myself, are apparently too alarming for the New York Public Library,” she tweeted. “So they will not take our money to rent a hall for a private event, where we planned to talk about women’s rights.”

According to the NYPL’s own mission statement , its goal is to “inspire lifelong learning, advance knowledge, and strengthen our communities.” That’s kind of hard to do when you have page after page of programming on gay and transgender issues but no interest in giving a platform for women’s voices to be heard.

That’s exactly why events such as “Evening with Canceled Women” are more important than ever.

“A growing wave of misogyny from the Left is celebrating prostitution, normalizing sexual sadism, re-stigmatizing lesbians, and gleefully erasing women in language and law,” the event’s description reads. “The consequences to anyone who speaks out are swift and severe, from deplatforming to death threats. Canceled Women will feature an evening of women who have refused to be silenced by the authoritarian Left.”

As the denial of biological sex has already become a tenet of progressive orthodoxy, women’s voices on the other side of the argument are increasingly silenced. J.K. Rowling faced a social media throttling when she dared to tweet in support of a British woman who lost her job for expressing belief in biological sex.

When rejecting the woman’s suit against her former employer, a U.K. judge claimed that a belief in the immutability of biological sex is “incompatible with human dignity and fundamental rights of others.”

That might have happened across the pond, but if even the public library is too afraid to let women tell the truth about biological sex, it’s not too much of a leap to think it could soon happen here.
