Two types of stupid were involved here.
First, a festival to worship Earth, and the second of course was there was alcohol involved.
People do stupid stuff a lot. There are a lot of them who believe the nonsense that we can either kill or save the planet. That is as narcissistic belief as the people who fly private jets around the world to try and stop it, and those who believe what they say.
I’ve heard of drawing on faces of passed out people, or covering them with whatever, but burying them alive? That’s a new level of stupid for me.
