I don';t quite see what the issue is with it, from a quick skim -- YES, they all seem to admit that they were treated better professionally once they transitioned. The 'more decisive' stuff about T, I'd possibly stick that under the what they think they're supposed to feel once they're 'a real man'. And let's face it, they're not exactly going to feel sympathy with the rest of us left-behind females as regards sexism, because that would clash with their desperate need to be accepted as a man.
What I take from it is fear -- because they either don't have a phalloplasty, or if they do know they can't fully pass once things get intimate. Hence the security they get from being able to walk the streets and professionally and 'pass' is forever waiting to be undermined if they want intimate relationships. Plus they realise they weren't socialized as males, hence don't know the unwritten rules of masculinity, and how to pass as men amongst men.
In many ways, even if they realise that they have a different perspective, and realise how different things are for chaps, they aren't free to say so without letting the cat out of the bag and explaining how they know. It's frankly internalised misogyny, part of why they so desperately wanted to escape femaleness in the first place. And whilst projecting it outwards onto females, they can try to not focus it back on themselves, because they so desperately want to believe that it not only no longer applies (because they are men), but it never properly did (because they were always men).
O, I know why the sense of betrayal is so hard to take, but whatever advantage they have gained is (almost always) at a hell of a cost, and as long as they cannot be openly a transman, there is always going to be the fear of being discovered and uncovered and 'sent back' to the position of lowly female they were so desperate to escape from.
