After religious organization fought the atheist advertisements, the city ruled that religious advertisements were no longer allowed to appear on city buses. This makes sense in the same way that religion is kept out of public schools.
But, here's my issue with the whole matter: why promote a message meant to dispel a person's belief? "Millions of people are good without God," the ad states. Then, why the need to proclaim it? If you are fully satisfied in your rationale and reasoning, there should not be a lingering desire to now "convert", for lack of a better term, those who still have faith in a God. Religion is an important aspect of our culture and to many it is an indispensable part of their lives. Energy spent trying to take that away from someone who is not physically or emotionally harming you is an utter waste, and does much more harm than good. Let them believe, let them be, and stop acting jealous.
