@masha-russia replied to your post “i’m not saying you’re wrong if you don’t headcanon modern gendry as…”
But why … His father is Robert Baratheon, a white man, and his mother was a blonde white woman …
Because it’s an AU and you can do what you want in AUs. Especially with Modern AUs, where all of GRRM’s worldbuilding goes out the window.
If you’re making it a modern AU, you can still have Robert Baratheon be white if you want. GRRM’s Westeros is one where whiteness is assumed, especially when talking about blondes, but this is the only information we have about Gendry’s mother:
The boy shoved a fresh fall of black hair off his forehead. "She died when I was little. She had yellow hair, and sometimes she used to sing to me, I remember. She worked in an alehouse."
GRRM did what he does with many mothers: made it so that she disappeared pretty early on in Gendry’s life. I’ve always assumed her “blondness” was to move counterpoint to Cersei’s. Which you can move to a modern AU if you want, or you don’t have to.
That’s the thing about Modern AUs--you can do what you like. For example, bastardy--something that stings Gendry heavily--is nowhere near as stigmatized now as it is in Westeros. That’s a major point of his characterization that just flies out the window when you AU him. Yes, you can (and people do) still write him as lower class to still get that “too bloody lowborn” element into his characterization, but that doesn’t mean that he’s going to be identical to his canon counterpart.
But that’s me going on a tangent from my main point:
You don’t have to have Gendry’s mother be blonde in a modern AU. And, if you do, women of color 1) can have naturally occurring blonde and red hair 2) can also dye their hair blonde, so young Gendry may remember his mother as blonde anyway. (For that matter, even if you do have her be a blonde white woman, why doesn’t she dye her hair to whatever fucking color she wants? Hell, we have many characters in canon who dye their hair, how do we know that Gendry’s mom didn’t henna her hair blonde in canon? Because literally we know fuck-all about her.)
Just because GRRM’s assumes whiteness in Westeros doesn’t mean that we as readers and fandom creators have to be bound to it, especially when racial politics in our world are so interesting and so frequently swept under the rug.
Why though? Because I personally find it more compelling for a character that I love to be biracial (or straight-up of color if you want to racebend Robert too which I’ve seen people do in a really awesome way (x) (x) (oh here’s arya and gendry of color too!)) in a setting where I can be as creative as I want to be.
