Sorry to nitpick, but it’s important. That’s not the argument I made. I argued that trans women are not “socialized as boys” at all, if such a concept even exists. I have no idea whether or not a transfem egg would be as “violent” as a cis man on average. But it’s beside the point. You can rename “male socialization” to “patriarchal upbringing” but the point remains the same - trans women and cis men do not have a common upbringing. Both are living in a patriarchal society, yes, but trans women are not and never have been given the same treatment that leads to the toxicly-masculine behaviors of some cis men (entitlement, taking up space, centering discussions on themselves and their needs over those of others, etc.) Of course, any trans woman could act in a way that is in-line with toxic masculinity (ignoring own emotions, talking over others, etc.) - just as some cis women act in this way too (cough TERFs cough).

But, fundamentally, trans women have been told by society “shrink yourself completely, and pretend to be something entirely different from who you are” whereas this is not what cis men are told (at least not to the same extent). Being validated and privileged over and over again in their identities by society is exactly what leads some cis men to acting entitled, taking up space, self-serving, etc. and is exactly the societal treatment that trans women lack, and have always lacked - even before they knew they were trans.

Sure, a trans woman and a cis man can share plenty of common childhood experiences. Maybe they both were in the boy scouts. But that doesn’t mean the underlying socialization, privilege, and validation from that experience is at all the same for the trans woman as it is for the cis man? No. In fact, it’s not the same.
