I mean you can get it or not it’s not a debate. Trans etiquette is something that a concensus of trans people request of other people and we set the standards based on how gender makes us feel, not how cis or even isolated trans individuals understand gender. This isn’t an exercise of strict logic. This is dealing with a culture of people dealing with a problem you don’t have and telling you where their pain points are. You don’t have to listen just like you don’t have to obey another culture’s etiquette when you are abroad… but expect to be treated as out to lunch or annoying to deal with. If I took you to meet other people in my community and you did that to one of their past photos I would be embarrassed on your behalf. If you did that to me I would probably not bring it up but internally wince because unless you were a friend I would treat you as a temporary inconvenience.

When someone says “I used to be a woman” my reaction is largely that is just incorrect. I never was a woman there was simply a stage of my life where I was afraid to be a man or unaware that other options were possible. In short - I was coerced. Other people identified me as a woman based on the sex characteristics I had and I identified as a woman because I did so out of fear of social reprisal or because I was kept in ignorance by dint of a society refusing to treat that knowledge as something I was allowed to have. Saying I “was a woman” would imply that I chose to do so freely, which I did not. Quite frankly when they look at a picture of me and read my past self as a woman it’s a reminder that to a lot of people that presentation and body type is all that they need to misgender me in a round about way. They are referring to a time when I was a prisoner to a system and identifying based on what they think I should be coded, not how I code myself. You think it’s fine to say I changed from woman to man because of social category and that it’s a construct - but to be honest that’s a pretty cis take. I react negatively to my SEX characteristics and use gender performance to stop people from bringing up my assumed sex characteristics into conversation. Language is a mirror through which we catch glimpses of ourselves. The mirror does me damage, I don’t linger in front of physical ones and I ask people not to use linguistic ones. When you call me “she” even in past tense you are referring to aspects of my body that I do not have the capacity to feel neutrally about.

I know a fair number of other trans folks who wish to expunge every pretransition photo from existence in part because they invite people to comment on this sort of temporal understanding of gender. If we could have you forget we were ever our birth sex we would. Instead most compromise by asking for a retroactive update.
