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).
Bob: "I'm going to wear a dress to work and call myself Jemima. Will you call me Jemima?"
Female co-worker: "Of course, I'm a nice person"
Bob: "Will you refer to me in the third person as she/her?"
Female co-worker: "Of course, because I don't want to upset you and I'm quite
happy to have a man tell me that I don't know how to use the English language correctly despite having spoken it without incident my entire life"
Bob: "I'd like to start using the women's toilets because I'll feel more comfortable"
Female co-worker: "I'm sure that won't be a problem because your comfort is far more important than any pearl-clutching concerns that us women may have"
Bob: "So you believe that trans women are women?"
Female co-worker: "Well I can't see the cost of me agreeing so of course I think you're a
woman in spite of you never having menstruated and being stronger than most women on the planet"
Bob: "I'd like to come on the women-only spa day so that I can sit in the hot tub with my lady cock out in front of all you ladies that don't have cocks"
Female co-worker: "er...of course, because it's a struggle for you being in a room full of semi-naked women whereas us women have no problem being used to serve your fetish...I mean 'helping to affirm your true self'"
Bob: "I'd like to join the women's rugby team that you also play on"
Female co-worker: "I'm not sure that's safe, as I'm 5 foot nothing and you'd flatten me like a pancake"
Bob: "That's Transphobia you terf bitch!"
