Black is only evil when people fall for the promise that it is slimming. It can be, but not in all cases and not all the time. Sometimes a given posterior is so massive that the gravitational effects disrupt the passage of light and thus the slimming effect of black is rendered ineffective. This applies especially to black stretch pants.
Channel 2 news in Detroit has a fat blonde weathercaster. This morning she wore all black. Then she stood in front of the big weather screen and was well-lit from behind on all sides. Then she turned sideways.
So...yah, black is slimming, but only in certain situmications.
As for the OP, it's transparently clear that black is night time, and there are actual, scary demons out there that love it because you can't see them when they are doing evil. So I support the declaration of black football jerseys as evil.
Demon 1: I'm bored. What should we do?
Demon 2: I dunno. Let's go corrupt some teens! Teen football players are all full of themselves! Should be a cakewalk.
Demon 1: Hot damn! Where are some?
Demon 2: Right over there, look!
Demon 1: Ahh, no. Noooooooooo! Oh, no, they're incorruptible because they're wearing orange.
Demon 2: Dammit! Damn that clever Sharron Angle!
