Do you see anything offensive about this ad?

Me neither.
It’s the poster for the Finland Atheist Bus Campaign — the sign translates to “There’s probably no God. Now stop worrying and enjoy your life”
It went up several months ago, and there were (surprise!) several complaints from religious people.
Yesterday, however, the Council of Ethics in Advertising (a Finnish advertising watchdog) made this statement:
Finland’s Council of Ethics in Advertising, a self-regulatory body that is part of the Central Chamber of Commerce, said Tuesday it did not consider the atheist bus campaign inappropriate.
…
“A campaign cannot be considered to be generally offensive just because individual religious people may feel it is,” said Paula Paloranta, the secretary of the Council of Ethics in Advertising.
It’s amazing these statements have to be made in the first place, but it’s nice that the group is making them.
Finnish atheists should take it as a green light to keep these ads going.
