Perspectives give insight into the "whys". You may not agree with the perscription, but understanding the diagnosis can be very enlightening. (For the record, I'm non-committal in either direction, atheism or otherwise).
And the "whys" will be answered by religion? I find that science does a better job of that. I'm infinitely more interested in physics and cosmology. As I have stated in other replies, I'm more interested in the negative aspects of religion.
