It was specifically created for that purpose - to show that innocuous statements would be met with hatred and accusations of evil because those people genuinely believe to be white is to be bad/evil

Just as the OK sign, drinking milk at all and bringing jugs of water around were meant to show how unhinged they were, IOTBW was meant to show they are genuinely bigoted and hiding behind a thin veneer of progressivism

I had a friend that used to bring a gallon jug of water around but that's because he played football in a very hot state.
