I’m saying there is a very strong pushback against the idea of culturally or historically significant figures who, based on their own writings and those of their contemporaries, may have had a gender identity which we today would recognize as similar to transgender although the language at the time may not have matched up precisely. The names you mentioned were individuals famous specifically for their gender identity and/or advocacy (not to mention that Marsha P Johnson did not self-identify as transgender). By all means, look at Alcott’s personal writings and come to your own conclusions but there can be no denying that the suggestion rankles people online.

People fucking HATE the idea of trans people existing before 1997.
