Things that used to be "NORMAL". (Though unfortunately, some still are.)

1. Slavery.
2. Indentured servitude.
3. Feudalism.
4. Women not allowed to wear pants, vote, own property, etc....
5. Work houses.
6. Witch hunts.


Virtually any cultural "norm" you can think of has been in or out of favor at any given time in history. So in that respect, I say bring on the strange. "Normal" does not necessarily equal "good".
