Sometimes you post something that seems so obvious, something inherently and patently truthful, that a reasonable person simply couldn't disagree with you, only to find that some misguided, deluded individual indeed does hold a contradictory opinion, and has must been waiting to pounce, spewing forth venomous threats and falsehoods.
Like this, from the BP archives:
Yolk Sac: Green sunfish suck.
JHAP: You Moron!
