In UK atheists considred more moral than theists.

[Mister Agenda]

What is an athiest's moral authority? What puts them on the same moral page?

Not getting our morals from someone who claims to be a moral authority. But asking this about atheists is a category error, as they same question would be if asked of theists (you'll get different answers depending on what god they believe in). On this forum, most of the atheists are humanists, who use their brains to figure out what is most moral based on what has the best outcome for human thriving.
