Transgender as it is currently defined is a recent thing.
The 'T' got added to LGB not so long ago - and without asking us LGBs first, I might add!
You wake up one morning and find that a whole other group of people that have little or nothing in common with you are now somehow stuck to you and they won't go away🙄
People like the mahu of Polynesia are men who live in a gender non-conforming way; which is not the same as claiming to actually be women.
'Third genders' are exactly that: not men claiming to be women or vice versa, but men and women operating outside gender stereotypes.
That's not the same as transgenderism, with slogans insisting that 'transwomen are women' and 'transmen are men'
The trans movement re-writes lesbian and gay history to invent a trans history - for instance the Stonewall Riots in New York in 1969, which were a key moment in the development of a lesbian and gay movement, have been 'co-opted' by claiming that the riots were instigated by trans people. Given that the term transgender didn't even exist in 1969, that's a bit of a push, but the Stonewall was a gay bar and the people who were there and resisted the police raid were lesbian women and gay men.
There's another infamous example, where a pro-trans slogan was photoshopped in 2023 onto a photo of the first lesbian and gay demonstration in Ireland which happened in the 1980s. Even more shocking was that the demonstration was in support of a gay man who was murdered in a homophobic attack. No respect, no shame, no historical accuracy.
