I am baffled as to why Zoe seems so ignorant about stuff that she must, surely, be aware of, if she's paying attention. Surely she must know there are lots of men identifying as trans who don't even bother to try to pass?
It's interesting that she explicitly uses the phrase "reducing it to the absurd", which Helen Joyce as a mathematician uses in Latin as "reductio ad absurdem".
It's a means of proof of a theorem - you assume something is true, then demonstrate that if that is true, then you inevitably reach an absurd deduction (more accurately paradoxical or axiomatically impossible). Which shows that it cannot be true.
So some people look at the "absurd" cases and think they demonstrate why a rule doesn't work.
Whereas Zoe and others think pointing out actual absurd cases, or even suggesting that they're possible, is somehow offensive.
The very concept of "reductio ad absurdem" is kind of rude. Why would you do that to a perfectly innocent theorem? Just leave it alone, let it "live it's truth".
