@Labadabbado "i grew up in the southern us in the 80s where homophobia was rampant." Thanks for sharing this it is actually super relevant. So without wanting to be patronising whether a change is progressive or regressive depends on where you are looking from.
Gender Identity is (from where I'm stood) both sexist and homophobic, but it is potentially, less sexist and homophobic that the southern states of the US.
Gender Identity is a theory that emerged from (gay) conversion therapy. The idea being that being homosexual was 'getting it wrong' and by fixing (strengthening) someone's gender identity you could turn someone back from a homosexual man into a heterosexual man.
Modern conversion therapy says that what you have isn't a boy with a 'faulty spirit' which needs breaking but a boy with a 'girl spirit' who needs treating as if he were a girl (which would feel kind and progressive by comparison) with body and hormones being medicalised where resources are available to make for the happiest healthiest adult possible.
GC (old school) progressive is different, we aren't coming from the same place.
sex - big categories inclusive important in some situations
Sexual orientation - kinsey scale (0-6) from super gay (completely homosexual) to super straight (completely heterosexual) but consenting adults treating each other with care and respect are free to 'the pursuit of happiness'.
Dress and make up are optional hobbies regardless of sex. Have fun with them if you like ignore them completely if you like it won't make you one bit more of less of a woman.
So for example new progressive tells my daughter she doesn't need to do high heels or make up because she's nb - old progressive tells my daughter that she doesn't need to do high heels or make up because it's sexist bollocks.
