"The modern world has slowly come to the fact that gods are artificial constructs. If such is the case, why should we worship the gods of our ancestors, rather than gods of our own?

Why Madoka? For one, we know her origin; we know she's 'false'; and we know what she stand for. The modern life, despite all its amnesties, is still full of despair and loneliness. Accepting her as our god allow us to envision a world that makes sense for our generation.
A beautiful god, a loving god, one whom will not abandon you, or admonish you for your mistakes and failings."
