So, peaktrans refers specifically to reaching the moment where someone who typically:
--has always supported LGBT rights
--has nothing at all against (post-op) transsexuals
--has supported post-op transsexuals being protected from discrimination by giving them certain rights, such as gaining legal status as if they were the opposite sex via the Gender Recognition Act or by having gender reassignment protected in the Equalities Act
--mostly had no problem sharing a toilet with the few genuine transsexuals (depending on presence or absence of past trauma involving males)
--who typically believes that post-op transsexuals is who the mantra "transwomen are women" is about and who while not necessarily agreeing on a biological, material level, is nonetheless willing to concede that they may be thought of as similar enough to women thanks to being post-op and mostly "living as women" for decades (whatever the latter means)
They are, in short, trans allies.
And then comes the moment where they learn that "transwomen are women" now applies to physically unaltered males the very second they declare themselves women. No social transition required, no medical transition required, not even crossdressing required.
And this happens via one of the many examples given above.
You reach, in other words, the moment where you are confronted with
--an extreme claim made by trans rights activists that seems so outlandish,
--a demand they make that seems so unreasonable,
--an individual example of a transwoman (and it is almost always a transwoman) doing something so horrifying that is excused, explained away or minimised by trans rights activists
that you find yourself going Hang on a minute...what? and first you think No that can't be right, I must have misunderstood. and then you realise that you didn't and you find yourself thinking This far and no further.
That is peak trans.
We typically fall off a cliff edge thereafter. Because once you start questioning one aspect, the whole ideology and its implications for women and girls unravels fast.
