Transphobia

A refusal to accept the tenets of transgender ideology as defined at this very moment in time - i.e., if you accepted them when it just meant not being mean to trannies but don't accept them now because you think (and can prove) that biological sex exists, then guess what? You're a transphobe! Used as a (decreasingly less successful) means of silencing people who think that segregating intimate spaces based on sex still has some merit (because babies tend to start falling out of vaginas 9 months after small gamete producing humans stick their wieners in large gamete producing humans and eject said small gametes).
