Curate, connect, and discover
Don't get me wrong, when I first heard it, I loved it. But there is one issue.
Harry can't be a POC
The reason people originally made up the headcanon was because 1.) the utter lack of non white people, 2.) the fact that it never specifically states he is light skinned, and 3.) Harry Potter could be viewed as an analogy for racism (with half-bloods and purebloods, etc...)
And that's great, but, if it were an analogy, Harry can only be light skinned.
Why? Because it has been stated that the Potter's were a pureblood family, so, in the analogy, they would be white.
You might be saying, yes, but James married a muggleborn, so Harry is a half-blood.
Okay but Lily had light skin as well. I'm not sure if it specifically says that, but she does have red hair, and I haven't seen a natural red headed POC.
Not being racist, like maybe there is someone out there, but it at least isn't common
So Harry just can't be.
Hermione, on the other hand
100% yes
okay carry on
