This is a Swedish ad which says "God probably doesn't exist." And then in a smaller font "yet he still affects you." Also, they've replaced the yellow Cross on the Swedish flag with the Muslim and Jewish logos probably in a way to demonstrate just how deep Christianity is rooted in our history.
Sorry if i hijack your thread now but do you think this kind of text would be considered "appropriate" in the US?
My personal thoughts about it? Well, as an outside observer I think it's good that ads like these exist. I'm aware of the mild discrimination that some atheists face and it's good that they find some place where they belong
