So the tricky thing — a “cult” can have many connotations.
First, to cultivate. Like to cultivate the land. Or to cultivate an idea, or to cultivate a group of people towards a common good.
Second — a worship group (like the cult of Dionysus, Bacchus) like the Danaeds who would worship Dionysus, get drunk and participate in weird orgies (consider Brave New World and the “orgy porgy” idea).
