„During bombing raids in Iraq, the media liked to say that Saddam Hussein used people as human shields. That's not accurate. Although it's true they were used as shields, the fact is they were humans already. So if these humans were used as shields, they were human shields. They weren't being used as human shields. Got that?“
— George Carlin

„Present-day students are often puzzled at the apparent contradictions of Southern slavery. One hears, on the one hand, of the staid and gentle patriarchy, the wide and sleepy plantations with lord and retainers, ease and happiness; on the other hand one hears of barbarous cruelty and unbridled power and wide oppression of men. Which is the true picture? The answer is simple: both are true. They are not opposite sides of the same shield; they are different shields.“
— W.E.B. Du Bois
