Many people just assume that everything they read is true without ever looking at the counter argument. Take a look at the flip side of some of these “universal truths”:

Universal Truth: Lying is bad.
The Flip Side: What about lying to save someone’s life? If your child wants to leave the house, but you know that the world is a place full of danger, is it wrong to lie and say there’s nothing out there?

Universal Truth: Do unto others as you would have them do unto you.
The Flip Side: Do nothing unto others. You don’t know where others have been. Others could have been playing in the toilet.

Universal Truth: The earth orbits the sun.
The Flip Side: Our planet is just a big rubber ball that a giant baby is playing with, and the sun is a night-light in the baby’s bedroom. Other planets are the baby’s other toys. Gravity is the baby’s hands.

Universal Truth: Don’t bring electronics with you into the bathtub.
The Flip Side: What if your phone is in a plastic bag? Would it still electrocute you? Would it?
