Okay, for some very odd reason, I feel like using the word "antiquated" in a sentence, but I can't think of a good one. Hmmm...

Many antiquated ideas from the past have become such due to social revolutions. Example: the sexual revolution of the fifties and sixties.

Islam's policies may seem antiquated and cause confusion to those who don't understand them. This can cause scapegoating due to ignorance and fear of the different.

Okay, I feel better now.
