They also treat socialisation as some indelible artefact of the past, not an ongoing process. Women aren't just more shy and cautious on average because they were taught that as small children; they're like that because of the environment they're still in at forty or fifty. It's not some irremovable childhood brainwashing, it's a reasonable reaction to current circumstances. A great many trans women become more shy and quieter after coming out or transitioning because the people around them socially punish them for not doing so, same as previously shy and quiet cis women become more confident and take up more space when put in environments that don't punish them for it. They act like someone's personality and behaviour are branded into them based on whether they have a penis at eight years old, but that is simply not the case.
Whenever I see people who are like "trans women are all loud and aggressive and uncouth (/negative)" I automatically think "do you think black women are all loud and aggressive and uncouth (/negative) too? Because that's what you sound like. You sound like someone who met two or three women from an oppressed minority that were more confident than you wanted them to be, and decided that the whole demographic was beneath you in a different way for daring to not stay in their place."
