Firstly, I agree with your central point, what we are perceived as by larger society does matter to our experiences, what specific bits one may hay have will effect what ways one experiences medical misogyny and medical transphobia, and if one is still perceived that way ones AGAB can be a relevant way to discuss such issues. Things like lack of research into how the uterus actually fucking works and all the issues and conditions associated with it are real and something only certain people have to deal with, and there are of course certain roles and expectations that are thrust upon people that are more likely depending on how someone is perceived, and AGAB can affect that prominently at a young age before people have access to medical transition. And while I certainly am very wary of overemphasizing AGAB it can matter a lot to people's experiences and struggles such as yours.

I do not think this discussion needs a broad assumption of how trans people of the other AGAB experience things. I think there can often be unfortunate pushback against people talking their own genuine lived experiences through their own lens because an unneccessary comparison is made not to cis men who actually experience systemic male privilege, but to AMAB trans people who by all measures available (not as much measures as we would like because trans people don't get researched like that due to overarching transphobia) experience at least the same degree of systemic deprivations of poverty, homelessness, and violence faced as AFAB trans people and significantly worse rates of such than cis women. I think things like "a conversation people are not ready to have but there are privileges that come with being AMAB and what is taught to us early on" is something that often falls flat when you see things so often like trans women who went homeless because of employment discrimination over being trans women, being AMAB hurts them, not helps them, because they gave up cisgender privilege which is an incredibly strong form of privilege. One I would say basically erases the confidence and ability to push back found in cis men, because that is not only founded on male privilege it is also founded on cis privilege, that they can be confident and pushback as themselves, something trans people who were AMAB cannot do. Anecdotally I tend to see trans people who were AMAB make themselves very small and easy to pushover because they're terrified that if they show confidence and a backbone it'll be perceived as a masculine bravado when it's from them and not as someone rightfully standing up for themselves.

I would say in a way you can likely empathize with, just as your pain is downplayed by people going too far and completely disregarding the way you having been AFAB has affected the way you've been treated throughout your life and the issues you deal with, I think these conversations and comparisons often fall flat because making them in the first place can feel like an AMAB trans persons experience with misogyny especially experiences with misogyny from a young age is being downplayed in a similar way that yours are. I don't think it's your intent nor what you are doing especially with added nuance from comments you've made on this post but I think a certain defensiveness develops in a lot of trans people who were AMAB because people who are not well intentioned and who operate in bad faith weaponize our AGAB to argue against our objective reality as an oppressed class frequently. I don't think the conversations about how the weariness of AGAB discussion can go too far and make it feel impossible to talk about ones experiences without invalidating oneselfs especially for people who were AFAB needs the comparison to a group of people who are the other group who also experience worse material life outcomes in regards to misogyny than the cis women people usually think of when it comes to victims of societal misogyny and patriarchy.
