Is Penguinism a Cult?

A lot of people think of cults when they think about religion, but a cult and a religion are quite different. There are religious cults, but there are also cults that are not religious in nature and religions that are not cults. The key features that differentiate cults from non-cults are clear group inclusion/exclusion criteria and maladaptiveness. Penguinism lacks both of those conditions.
