To get on the wrong side of transgender activists is often to endure their unsparing criticism.

After a Democratic congressman defended parents who expressed concern about transgender athletes competing against their young daughters, a local party official and ally compared him to a Nazi “cooperator” and a group called “Neighbors Against Hate” organized a protest outside his office.

When J.K. Rowling said that denying any relationship between sex and biology was “deeply misogynistic and regressive,” a prominent L.G.B.T.Q. group accused her of betraying “real feminism.” A few angry critics posted videos of themselves burning her books.

When the Biden administration convened a call with L.G.B.T.Q. allies last year to discuss new limits on the participation of transgender student athletes, one activist fumed on the call that the administration would be complicit in “genocide” of transgender youth, according to two people with knowledge of the incident.

Now, some activists say it is time to rethink and recalibrate their confrontational ways, and are pushing back against the more all-or-nothing voices in their coalition.

“We have to make it OK for someone to change their minds,” said Rodrigo Heng-Lehtinen, executive director of Advocates for Transgender Equality. “We cannot vilify them for not being on our side. No one wants to join that team.”

They cite tactics, especially on social media, that became routine for devoted backers of the movement: Attempts to police language, such as excising the words “male” and “female” from discussions of pregnancy and abortion; decrying the misidentification of a transgender person as violence; insisting that everyone declare whether they prefer to be referred to as he, she or other pronouns.
