Be consistent with your shit.
If you subscribe to the idea that Katniss is a woman of color then that means Gale is a man of color. And that means that the way this fandom at large deals with him is gross. He’s a man of color who’s fighting for the rights and freedom of his people, for fuck’s sake. To hear some people talk, you’d think he was the villain of the text.
If you don’t like him, then don’t like him, that’s fine. But being a person of color goes both ways. Maybe no one else in fandom cares about men of color who want the revolution to begin but I do.
Deal with it.
