The trouble with your “counter perspective” is that it doesn’t allow for the actual truth of the experience. How could it? You didn’t live it.
Not only are trans girls shamed for expressing femininity - they are taught they are inherently inferior to BOTH cis boys AND cis girls and systemically deprived opportunities for socialization, bonding and camaraderie (fitting in generally) from nearly everyone in both “camps” and often at home.
Trans folks are raised to know who they are NOT as much as they are raised to “act as” what they’re told they are, while being recognized as not “enough” of either. If this sounds delightful and “preferable” to you, so be it. It wasn’t.
