[Comment in response to a blog post about a high-school club called NRS Club, for NonReligious Solutions.]

Distributing Christian Flyers and the style of flyers themselves may be offensive, but the core of Christianity itself goes against offence. The whole purpose of Christianity to tell people not to offend each other.

On the other hand, putting up posters about atheism or distributing flyers about atheism, or the style of the flyers themselves may not be offensive, but the core premise of Atheism itself is to offend theists. (The semantic argument of whether Atheism is merely a lack of a religion is irrelevant here.)

Christianity – and any other positive religion or moral philosophy – seeks to unite; Atheism seeks to divide.
