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 must have been just waiting to pounce on your innocent contribution, spewing forth venomous ad hominem attaks and falsehoods.
Like this, from the BP archives:
Yolk Sac: Green sunfish suck.
JHAP: You Moron!
