As an atheist, I do feel that atheist groups are rather pointless. I do not oppose religion, I oppose the effect that large groups have on individual, impressionable people. There are, however, individuals that are persecuted due to their atheism, either by their families or by their communities. However, an organized non-religion can be just as bad as an organized religion. I support the freedom of the individual, and a specific group for atheists infringes on that part of my person.
And I drive a Honda Civic. 1991 Civic DX to be exact. It is a fantastically slow car, but it treats me very well and I treat it very well in return. It makes up for its sluggishness by averaging 37 MPG. Mostly city driving. If I take it out on the highway, I'll get 45+
