In Australia, atheists hoped to put up bus ads saying "atheism – celebrate reason" or "atheism - sleep in on Sunday mornings", but they were banned by the advertising company.
Why, you ask?
Metro has previously allowed adverts from religious groups including anti-abortion campaigners, but says it has now changed its policy to ban all material deemed controversial.Basically, they get carte blanche to censor whatever they don't like. Ridiculous.
But it's not like this reaction wasn't expected - they gave it a no wayback in November. I guess it's just official now.
