How was that wrong? I was pointing out his stupidity in a teasing manner, replicating his own behavior. That's what people get for being e-tards.

See how that doesn't really work? Being "teasing" doesn't doesn't change the fact that you were an starfish.
If you had just kindly pointed out his error, it would have gone a lot smoother.
