She also doesn't consider that just because trans women are socialized as males in the early part of their lives, it doesn't mean that their experience is not legitimate. For example, when I was a kid, as paradoxical as this may sound, I actually liked being a "boy" and I thought that being a girl or anything associated with girlieness was bad. When I saw commercials on TV directed at my age group, I got the message that boys are cool, rational, creative, and smart, whereas girls are nothing but a bunch of prissy sissies that do nothing but gossip. When I saw myself as an adult though, it freaked me out to think of myself as a gross, hairy, smelly man. I wanted to grow up into a beautiful woman. From my perspective, being a girl and a woman were different because I was exposed to negative messages about females my age group, but not so much for adult women, since as a child I mostly watched kids' programming. I was a very confused kid because even though I secretly longed to be female, I repressed it due to the negative messages I got about it. A lot of cis girls suffer from the same thing, because those same messages that are drilled into their head, leading to internalized misogyny. For example, I hear a lot of girls my age talk about how girls are catty and superficial and how they love being friends with the guys because they are "drama-free". Just because trans women are socialized as male doesn't mean that their experiences aren't valid.
Also, I believe that being socialized as male isn't a liability, but an advantage, because trans women have first hand experience of the social constructs that surround maleness and masculinity, which are relevant because it's those social constructs that contribute to the oppression of women. For example, being socialized as a male, I've observed that it's very common for men and boys to look at femininity as some sort of awful disease, to be avoided at all costs. Also, a lot of guys see femininity as being contagious. Just merely being around girls is enough for it to "infect" you. The only way to make oneself immune is to either have sex with them, or treat them like a sex object. If you're not sexually degrading women, their femininity is gonna infect you and turn you into their gay shopping buddy. This is very relevant to the oppression of women, because a lot of the reason men treat women like sex objects is because society expects them to. I believe feminists ought to see being trans as being a huge advantage, because of the fact that you pretty much get to spend a good portion of your life "undercover" as a male, and get first-hand exposure to the social constructs surrounding maleness and how they oppress women.
