"RELIGIONS ARE JUST ANOTHER FORM OF SUPERSTITION."

This is not only a stereotype but a misuse of the term.

Many atheists and anti-religious people use the term 'supersition' as a general all-purpose smear against faith. Their use of this word is such that many display a clear lack of understanding about the religions they berate, as well as the true meaning of "superstition" itself.
"You need to realize that when you dismiss something that is a huge part of my life as 'nonsense' or 'superstition,' it hurts. You drive a wedge between us when that happens."
- "Poyemkyn," from the Ornery American forums
