The difference between fantasy and phantasy is:

1. Fantasy uses fantastic circumstances to convey real world truths.
2. Phantasy is escapism which distorts how the real world works.

Fantasy messes with the rules of physics.

Phantasy messes with spiritual, moral, and wisdom rules.

Fantasy has talking animals, flight, and hurling fire balls

Phantasy has sin with no consequences, rewards for foolish behavior, and gender-swapping.
