It wasn't an accident, actually, I am entirely aware that TERFs use "female socialisation" as a dogwhistle but the thing about that is they use it wrong and there isn't actually an equivalent term.
Socialisation is a specific mechanism of social reproduction. An individual is socialised as X; an individual is not socially reproduced as X. Social reproduction occurs when individuals are socialised along class norms. They're different but related concepts.
TERFs use the term completely cackhandedly and end up meaning something almost opposite to what socialisation means in every other context - "fe/male socialisation" per TERF ideology is something static, essential and immovable, whereas socialisation is meant to describe an active and continuing process.
Gender in specific is a site of multiple progressive resocialisations even for cis - enforced gendered behaviour as a girl child is different to enforced gendered behaviour as a teenage girl is different to enforced gendered behaviour as an adult woman is different to enforced gendered behaviour as a post-menopausal woman, and the same is true for boys/men, and the fact that gender is perpetually reenforced through social norms, and that the gendered role you're socialised towards changes throughout life and therefore we're in a perpetual state of active social conditioning, is a pretty foundational argument for gendered socialisation in toto being a social construct and therefore mutable/reassessable.
Sorry to get heated because I do understand where you're coming from, but frankly a) you're being really fucking condescending and b) I am sick to the back teeth of being expected to cede basic feminist theory and language to a minority of fucking idiot bigots who willfully misinterpret it into an antifeminist form.
Obviously my main beef with TERFs is that they're committed to fucking up trans people's lives for no reason except blind bigotry and an unwillingness to accept the necessary discomfort of questioning their unexamined bias. But a close second is that the ascendancy of TERF "feminism" has set actually useful feminist conversations back decades (not to mention the targeted impact on survivor services and lesbian/dyke/queer spaces).
Giving ground to reactionary bigots' bad faith interpretations of useful ideas and going 'well I guess that's TERF shit now' doesn't fucking help. What that does is help play into the illusion that TERFs are the Real Feminists because they are gradually claiming a monopoly on the aesthetics and language of more and more feminist conversations.
Where possible, we should examine our theory and language and steer towards clarity. And sometimes that will mean picking a synonym that's been less co-opted because that cooption does become part of the meaning.
However, in this case, I mean socialisation. As in the process of social reproduction through regular classed interaction and mutual conditioning. I don't mean social reproduction and I don't mean social conditioning, I mean the specific process of learning-by-doing around social role.
"Gendered socialisation" doesn't mean "an innate and insurmountable fate to end up the gender you were when you were 2" and the pretence that it does is legitimately incoherent in relation to the Actual Words Being Discussed. And given that it's quite an important process to talk about to understand a social model of gender as class, I'm pretty comfortable choosing that as a hill to die on.
It's worth interrogating. I have interrogated it exhaustively and talked it through with a lot of people. You're not introducing a new concept here. I just am not willing to pretend words mean whatever bigoted assflaps want them to mean when they have Actual Specific Utility.
