There are urges. But that's it. The adjective "natural" doesn't add anything to it. Saying that urges are natural and therefore going against them is unnatural ergo "bad" is mere wordplay.
In any case, my argument is that the things described in the picture (go to church, send your kids to sunday school, follow the bible, behave traditionally, get married to opposite sex, have children, spread the gospel, never disobey the lord) are neither urges nor natural. They are commandments of social indoctrination.
Eating, having sex etc ARE urges, but they aren't specifically natural or unnatural. They are occasionally individuals that deviate from these urges, and they are literally as natural as anybody else (since natural by definition means "coming from birth")
To say that "behaving in accordance with tradition" is literally the same thing as "eating" or "drinking" by reducing them both to the abstract notion of a "natural urge" is a logical fallacy.
