When we talk about relinquishing the world of religion, we should all realize that we are proclaiming war on a set of ancient ideas or thoughts, rather than groups of people. Richard Dawkins gave these sets of inheritable thoughts a name, Memes, which he defines as "a unit of cultural transmission, or a unit of imitation." These ideas, or memes, jump from host to host at such a rapid rate that it is nearly impossible to prevent or control, or even predict. The result of becoming infected by such a meme varies depending on the host, with consequences ranging from global humanitarian efforts to genocide. The first question we need to ask ourselves concerning the war on religious/viral memes is: SHOULD we try to end religion? Should we even wish it? We need to acknowledge the fact that religion has many positive attributes (hence it's quality as an addictive substance), and has benefited society regardless of its deluded intention. If we kill it, will the humanitarian efforts of general society go with it?
Therein lies the problem many atheists face in even confronting a religious individual on the contradiction within their faith. It is like approaching an alcoholic with their drinking addiction. Religion is a placebo to the public, an emotional crutch. As much as we might like to see it disappear overnight, it can't--nor should we wish it--because it is an addiction that has raged out of control. Like any addiction, regardless of the instant gratification it offers, it is dangerous to the individual as well as his peers. This is the reason I feel we should work toward relinquishing religion, but the war we claim is one on the idea rather than the individual... and we have haunting tales in our past of pursuits just like it. Witch hunts and heretic burnings... even the war on terror. All wars to end a thought, and all done improperly. How do we kill a thought? We replace it with a better one.
I believe that the key to curing the population of its religious dependency is EDUCATION. The Western world is by far the most liberated, and regardless of its deeply entwined religious roots, we are seeing just over 100 years of secular education undermine the control religion had for over 1000. It is truly time for secular education to travel into 3rd world countries, where religious fundementalism threatens the well-being of every living thing on earth. It is unfortunate that 3rd world rulers are allowed to benefit from the technology of the Western World (nuclear arsenal) without the requirement of secular education... which should highlight a sense of urgency to spread education in these highly volatile regions.
I do think we need to wish for the end of religion. I think we should work toward weening people off of it, and I think its presence threatens the future of human growth and evolution. If you think differently, let's have it :)
