If gay is for men (since according to you gay=gay MEN) then defining a lesbian as a gay women would be calling them a gay man woman. And since in this lingo world lesbian is referring to feeling like a women or identifying as one since its it is saying non-man, or non standard man. The word Gay puts men as the gold standard and since it is using man, and not non-woman or some form of “identifying as men” it is referring to biological males. Meaning gay means men born as men liking men. And lesbian means gays, aka past men, who like women. Its simple math if gay = gay man, then gay women = male women. which is basically saying women born as men liking women. It completely cuts out women born as women who like women and also cuts out males born women who like men. We went from something was fine for everyone to just cutting out two groups of ppl and thats the serious answer. If men are the default then what are women? The secondary option, that puts men on a higher plane. If you mean to say its the default is the sense that man=human and refers to everyone of every gender, then that destroys your own definition because non-man would not be referring to gender, it would be refreshing to their humanity. Which damn, ik i wouldnt want to be caught saying that lesbians are non-humans. Also we are not talking about the origins of these terms, we are talking about a brand new redefinition that is actively taking modern times into account over what has been done in the past.
