What’s a cult? It just means not enough people to make a minority.

Meaning of the quote

This quote by American director Robert Altman is saying that a "cult" is simply a group that doesn't have enough people to be considered a minority. In other words, a cult is a small group of people who have beliefs or interests that are different from the majority. The quote suggests that as the number of people in the group grows, it stops being a "cult" and becomes a recognized minority.
