During my time in high altitude astronomy, I routinely witnessed workers breathing medical oxygen, industrial carbon dioxide, nitrogen and helium gas as part of their daily work routine.

The only marches I have ever witnessed under a banner of so-called 'Christianity' have been to enforce oppression and incite hatred and intolerance - and to deprive people of their equal civil rights.

Hey, ghosts are nothing to laugh at! Whether or not you believe in them, they’re out there. I’ve seen them. I’ve even heard them.
