As an atheist, i'm right there with you on that.
However, i think i've come to the conclusion that religion is just the mechanism/means by which this evil is unleashed.
I think it's fundamentally about people trying to impose their will upon others because they think they are "right" and that somehow gives them some insane divine authority to impose their beliefs on others.
I'd advocate the eradication of all religions and the enforced teaching of science; except i'm sure that 100-500 years down the track we'd face exactly the same conflicts, just with minor differences in methodology or interpretation of results at the centre of it rather than who is the messiah or who should be the caliph.
I mean the big JC really only advocated 2 things: Love Thyself, & Love Thy Neighbour. And (us) Christians all managed to **** that right up for the last 2000 years. I suspect science won't fair much better, until the underlying issue is fully addressed.
Maybe it would help if we were at least attempting to think rationally though.
At this point i'd probably stick with: **** All Institutionalised Religion.
and: Violence begets Violence.
Hope springs eternal...
