Experience Tumblr like never before
You know, it annoys me every time someone calls Billy a racist asshole, he wasn't, I know for a fact he wasn't.
He never once said anything racist, never acted out in disgust at any other black characters, not even Lucas himself, not Lucas' family, not any background characters, non of that, he never made any comments about race either,
And don't bring up the "That kid is one of them" into this, because do you know what he saw? He saw some random kid arguing with his sister, he saw some kid making her upset to the point she walked up to the car teary eyed and tried lying about what happened, that's what he saw, he stood there in the background watching the entire time and I'm sure he may have heard a thing or two due to their arguing, Max said it herself that Lucas treats her badly, that is what he saw and of course, despite him taking his anger out on her, he cares, it's shown he cares because he saved all of their lives by sacrificing his own in the end.
Billy was never racist, he just didn't get the full picture of why Max was already walking to his car damn near crying when they've just moved into the town.
Tldr: Billy wasn't racist, just saw Max coming to his car nearly crying and thought she was being bullied already.
