This is incredibly naive and short-sighted.
Link is an avatar. Miyamoto, Aonuma, etc. have stated this themselves. It's in the damn name, he's the "link" between the player and the world. This isn't something we made up, it's literally the analogy used for him by Nintendo. Link is meant to be "you." You name the character at the beginning of the game.
Yes, the series was made with a male audience in mind. That's not a problem in context, it's how things were in the 80s and it's why most of Nintendo's long-running franchises feature male leads. But that's no excuse to leave things as they are; they need to grow with the times and the player bases. Pokemon started with a male lead, then Game Freak noticed that girls were also playing and introduced female options from then on. Why can't Zelda do the same?
As is in what you quoted, Link is not the same character every time. Nearly every Zelda game has a different character being used as that game's "Link," much like the Pokemon protagonists are never the same character as before. This is not the same as Mario, Sonic, Donkey Kong, etc. because those are the same character every time, and they are not avatar characters, again, as I said in the post you quoted.
I'm not asking to change the current Link at all. Did adding Leaf in FireRed/LeafGreen change who Red is? No, of course not. Why would it be any different with Link?
I don't like pulling the "male privilege" card, but have you any idea what it's like to be a girl playing a game as a character that is meant to be "you" and not even be able to have the character be a girl? It's happened often enough throughout history that many are desensitized to it now, and male gamers who always play as male characters rarely, if ever, run into this problem for their gender.
