The USA person first letter, he says that sex 'designation' is based on a mix of genes hormones etc. (I have put the quoted at end of this post).
When did he realise that male female as broadly defined groups are just not as straightforward as dick/ fanny/ sperm / egg/etc?
Age 8? 14? 25? Or has this fact that sex is designated and ill defined come to him more recently? Like around the time transgender as a topic crossed his path?
And assuming that his understanding of male female before that was the old widely accepted one. IE want a puppy? Need a penis dog and a vagina dog pretty obvious...
Then when he came across something NEW ie the idea that human beings as a species cannot be categorised generally into two sex groups, it's waaay more complicated than that..
Did he apply his sceptical approach to the NEW claim, IE that sex as a binary for humans, mammals, loads other animals plants etc is not valid?
That the way that humans have understood it as the most basic difference between humans for thousands upon thousands of years all over the world is inadequate?
If not...
And yet he's 'skeptical' of the definition up until 10 mins ago having any value...
Then he's not a 'Skeptic'.
He's a man with massive bias, credulity, blind spots in thinking, unquestioning on a matter which screams for questions.
And having read his letters, and despite the logical * FACT that he is about as sceptical as a tube of smarties. He clearly sees himself as intellectually superior, a man of objectivity, rationality, excellent judgement and impressive communication skills.
Hellooooo bog standard fella with over inflated opinion of himself...
*(IF there is loads of writing on when why and how he decided sex complicated/ designated I take it all back!).
Quote I was thinking of last night, how sceptical was he when heard that?!
'Sex designation is based on some mix of biological features like genes, hormones, and body parts, though there is often inconsistency in which feature is the truly essential feature,'
