"The most infuriating assertion regularly made by the "trans women are biologically male" camp is that trans people are somehow "denying" or "erasing" biological sex differences, and that this hurts cisgender women/“biological females.” This is patently untrue. I can assure you that trans people are highly aware of biological sex differences — the fact that many of us physically transition demonstrates that we acknowledge that sexually dimorphic traits exist and may be important to some people! I would reframe things this way: Transgender people often have a more complicated relationship with our sex-related traits (as they may be discordant with our identified and lived genders), and thus the language that we use to describe or discuss these traits may seem arcane, or nonsensical, or unnecessary to the average cisgender person. And because they are unfamiliar with this language (and/or flat-out antagonistic toward us), some cisgender people will subsequently misinterpret this language and differing perspective as some sort of "denial.""
