“Love each other” is almost certainly not the main idea of Christianity (rule? perhaps). The main idea of Christianity is that you are inherently in a state of sinning, and that Christ has sacrificed himself to atone for your sins: if you accept Him, you will be forgiven your sins and accepted into the Heavenly Kingdom. If you do not believe in (or know of) Him, you will burn for eternity in the pit of sulfur.

That's the main idea of Christianity.

Myths are stories, events, and characters people believe in. "Love each other" is not any of these things.

The myths I'm referring to are the ones involving virgin births, resurrections, and hilariously human-like deities who rule over mankind like invisible sky wizards.

But I think more people are starting to incorporate the idea of love without the baggage that might come with a religion.

that's also the main rule of like... common sense -.-
