"typical behavioural characteristics’ is not a sex category. HTH."
'Sex' in essence is about distinctive characteristics between the sexes that you clearly believe hence the demand for single sex spaces. The idea that only the body & not the mind evolved differently for survival & reproductive purposes between the sexes is ludicrous.
"Stereotypes are just a descriptor of group level observed behaviours. They change across time and location and are not definitive of anything."
You seem confused. Stereotypes are societal expectations that are oversimplified, often inaccurate, belief about a group of people, while typical behaviour refers to the common patterns of action observed in a population without being a rigid, fixed assumption, they are observable trends that don't discount individual differences.
"They change across time and location and are not definitive of anything."
'Changes' that aren't evolved are influenced by environmental/societal pressures. Behaviours like 'aggression' can be tempered & managed but they can't be eradicated without evolutionary pressures involved which is unlikely so the idea there are no stable behaviours is false.
In any case, that behaviours change is irrelevant to the point of 'sex' being about characteristic distinctions. Definitions rely on social usage & given societally we usually don't rely on gametes or chromosomes to distinguish men from women in social situations implicates the use of behaviours such as surface level presentation being a definitive sex distinction.
"I noticed one sentence where she started talking about ‘sex’, then replaced that with ‘gender’ and then ended it with ‘gender identity’ - all purporting to be the same thing. Total dishonesty."
Like I said from the start, if the frame of reference is flawed to begin with it's impossible to follow the nuances involved not to mention the obvious bias against doing so. One only need read Bindel's 'reaction' to the debate as "being in the presence of evil" & others enthusiastically nodding along to notice the amount of hyperbolic demonising hysteria of perceiving HW as "evil". If the standard of "evil" is unintended harm of others then one could easily apply that to GC ideology.
That consensus based medical treatments evidenced on data & clinical experience maybe eventually proved as harmful isn't "evil". It's just misguided.
As Bindel showcased, GC ideology relies on appeals to the extreme & dehumanisation & demonisation of not just trans people & their advocates but the medical profession. Always pointing to the extreme perverse rarities to smear & delegitimise. Six foot man following a child into the loos? Seriously?
