Transsexual refers to trans people in an explicitly sexual way and puts a heavy emphasis on genitals and sexual characteristics
i think most people use it without the emphasis on genitals (notice how there is not mention of genitals in the word transsexual). and even if they do, who cares? how does this erase identities or empower transmedicalism? just because you are uncomfortable with a word doesnt mean it cannot be used by anyone
I feel like you are really hung up on sex as to mean "biological" but I want you to consider that this (perceived) distinction between sex and gender is precisely the part that’s harmful to trans people. By separating sex into its own "biological" "scientific" reality you are missing that sex is as arbitrary as gender. Who is to decide what are sexual characteristics and what is not?
