Yeah that "it'd look the same" logic falls apart when we got people asking for a black link or a link that isn't hylian. What's the excuse then? "It's still the same character in spirit!"
Changing link to a female is just a excuse to change him even further which in turn would be taking a highly iconic character and destroying his design.
link as a girl is a gateway drug, kids. one day you're minding your own business on your stoop and a guy walks up to you and says he can make link a girl, for free. you say yes because that's something you've always been interested in and when you finally play it it's pretty good it lives up to the hype.
the next day the man walks up to you and says "holy shit, you've got to try this. link as a black woman."
"Whoa, that sounds like pretty hardcore stuff, is it safe?" You ask, weariness in your voice.
"Is it safe? I got this shit special for you. It'd be a shame if you didn't try it."
You play the game and it's even better than Link as a girl. You spend hours playing it, but soon you feel a slight weariness. You see the green cloak, and pointy ears, and enough of them still seems like Link, but...
Three Weeks Later
You're hiding in the laundry basket again. He hasn't been able to find you here. You pray that you'll go another day without hearing his voice, and the sweet things he offers. The withdrawal is torture, but at least Link is mostly in tact. The sanctity of Link is still in place. It can still be saved, if everyone just remembers what a terrible mistake all this was. But you feel it, then. The indescribable urge.
He's found you.
"I want you to see this," he says, eyes burning holes in your defenses. You feel weak. Your breath is fast and uneven.
"Get this. Black. Lesbian. Transgender....plus sized Link."
Your eyes widen.
My god, they've finally done it.
"And she don't even have pointy ears."
You fall down to your knees, sobbing, unable to hold back the tears.
You finally really did it.
YOU MANIACS! YOU BLEW IT ALL UP! GOD DAMN YOU! GOD DAMN YOU ALL TO HELL!
