Here's the thing, though. This is going to veer into some gender studies bullshit territory, so I apologize in advance.
Being "socialized male" does actually mean something. For whatever reason, men tend to dominate mixed-gender discussions more than women.
Multiple studies have been done on this phenomenon. Men expect to be heard out more in discussions than women and, even without realizing it, may spend more time talking than women in the same room. Now, this is again not a conscious thing on behalf of dudes, who quite likely have no idea that they're doing it, nor is it a hard and fast rule. But it is something that happens a lot to the point where social scientists know that it's a
thing.
Transwomen were treated as men before their transitions. Living as men, they were encouraged, in subtle ways, that their voices deserve to be heard and that they are entitled to be heard. Transmen, who were raised as women, were likely to have the same subtle messages telling them to shut up and let the men do the talking. I don't think it's any coincidence that transwomen tend to dominate discussions of transgender issues to the point where some people aren't even aware that transmen even exist. Transmen will find themselves demonized for having "male privilege" (despite being perceived as female pre-transition) and called transmisogynists or truscum while transwomen are held up as peons of the community capable of doing no wrong. Transwomen are having that socialization they learned as men ("what you have to say is very important and everybody should listen to you no matter what crazy bullshit you say") reinforced. I suspect that transwomen probably don't pick up on that unconscious bias towards listening to men over women until they pass well enough that nobody would even suspect them of being tranny.
A lot of people like Sophie like to downplay the socialization aspect because of the uncomfortable implication that even as women, they're benefiting from a kind of male privilege. That even as women, they still have the entitlement that many men feel they have. They want to plug their ears and pretend it's not a thing, but if I've learned anything from watching the transgender community, I'd have to say it is very much a thing. Sophie LaBelle is this phenomenon incarnate.
So of course she wants to pretend it's not a thing so that she can continue being the most oppressed ever.
