Quote - I've never understood why atheists defend "nothing" as if it were a something.

And I never understood why religious people defend "nothing" as if it were a something. So I guess we are in a strange sort of agreement there!

Quote - I can see a religion urging its adherents to go out and convert, but why do atheists even care?

 

Because it is good to care about things, about the truth, about people, about the world we live in. Caring is life enhancing, and if you care about the right things it can make the world a better place. I think that even many religious people would agree on that point.
