This also extends to heavily male-socialised trans men, from observation.
And
trans guys who, without wanting to throw shade on several of my mates, demonstrably exude trappings of male socialised privileged behaviours and make women inherently nervous by being present in their spaces
Transmen are not male socialised. The same argument for gender non-conforming boys who are bullied and grow up to become transwomen applies. Being unhappy at the allotted socialisation is normal for all people, gender non-conforming or not. Transmen grew up as girls, and are aware of their inherent vulnerability. Transmen also have a lot of internalised misogyny. Transmen and "non-binary" girls/women display an awful lot of "not like the other girls" behaviours.
I'm a butch lesbian, I have lived with dysphoria and I have lived through the internalised misogyny. Guess what? When you are very masculine, you don't get looked at by men in the same way and it's quite freeing. You can walk about without feeling like you're on display. You can be invisible. That's a huge motivator for girls who are fed up feeling like a piece of meat.
But as gruff and as rude as some transmen can be, and some I know are like caricatures of the worst type of man - that's not the same as being male socialised. Growing up with different expectations to those placed on boys has an effect, whether the individual succumbs to those expectations, makes peace with them or rejects them entirely. And again all women do this to some extent in their lives, because the requirements of femininity are too demanding to live out 24/7.
So no, roid rage and a beard and referring to women using derogatory terms, and belching and farting and manspreading don't demonstrate that a transman had male socialisation as a child, it's probably more likely that a transman, being female, is socialised to observe behaviours, recognise and replicate them. Quite often, like I said, it looks clunky and awkward, like a woman aping a fourteen year old boy. But quite often the approximation of behaviours, along with the requisite facial hair, means that transmen "pass" to disinterested strangers. As many gay men have pointed out, they don't pass to men who are actively assessing them, it's just that looking like a man means you can walk around largely unobserved.
Either: Trans women are inherently dangerous predators with transparent psychological attributes of maleness, or: there are no psychological attributes of maleness because gender isn't real, and all behaviours are constructed. Which is it? These can't both be true.
This is a false dichotomy, gender isn't what causes men to be more dangerous than women. Otherwise your transmen friends would commit crime at the same rate as men do, which isn't the case.
If we are talking about learned socialisation, then I profoundly agree; toxic behaviours imprinted on people by the patriarchy are indeed astonishingly shitty. However, if I express the experience of having been victim to them, I'm appropriating womanhood and they can't possibly be real
Again, you might have been subject to certain experiences if you pass 100% of the time, you might be subject to homophobia if you don't (if a stranger reads you as an effeminate male), and you haven't been socialised as a girl.
