Good job being a pedant.
Thanks. As this topic is about tagging, I dare say it is all about pedantism.
I mostly agree with this here
https://en.wikipedia.org/wiki/Person_of_color#Criticism
Especially this sentence:
Preserving "whiteness" as an intact category while lumping every other racial group into an indiscriminate category ("of color") replicates the marginalization that the term was intended to counter.
In my own words, racism is a thing to be abolished. But terms like that do not help, quite to the contrary. Oh, and I also do not approve of adding letters to lgbt for the same reasons.
do you know why the female-protagonist tag exists
Do you? Or did you assert your own theories after the fact?
My take on this is as follows. The same reason why indie and rogue-like or pixel-art are tags. Because people figured, you can sell games with that kind of pitch. To look special, to differ from perceived mainstream. (Tagging indie on itch is kinda overkill, but still 15k games tag it)
Because representation used to be a major problem in games.
It is not about representation. That is a problematic mindset, be it for games, movies or whatever. You need representation in democratically elected entities, not in other things. Crying for representation elsewhere is forced diversity and inherently flawed. By what standards would you apply representation? Speaking of things like ethnicity for lack of a better word.

There are more groups than cast members in any given movie/game. Representing is futile. And chosing whom to represent is a sure way of offending people. Either you do not represent them, so you offend them for not being represented. Or you represent too much of any group, so you get called racist. Or you go by diversity checklist and get called woke. Or you try to represent group A by chosing one of group B and offending both by doing so. But whatever you do, as soon as you chose by discriminatory attributes you are racist by defintion.
But back to female protagonist representation. Wich females would there be to represent? I play games for decades now and I do not have the impression that protagonists of the female persuasion are in any way underrepresented. One can complain that Link is the hero and Zelda is the princess, but if you have a scenario that losely has a questing knight, well, there were not really female knights in any significant number. Also, only games with fixed protagonist would qualify. Like Zak McKracken. But look further and you have the females in Maniac Mansion. Many games have fighters as protagonists and it is just unrealistic in many scenarios to have female fighters. It is easier with magic, contemporary or science fiction. Metroid is from 1986 and gave us Samus Aran.
As to why, well, males tend to want to impress females by doing stupid things (like going on a quest to slay the dragon). And such stupid things make a good story. A woman setting out to kill the dragon to be allowed to marry the prince... I have doubts this would fly.
