I've taken a cursory look around this forum and I have to say that I'm a little concerned. A lot of what has been said on these forums is derogatory and patronising rather than constructive and insightful. It seems to me a lot of you guys have abandoned one form of fanaticism and adopted another school of faith-based belief - secular humanism. The belief that dropping religion and looking to the future with nothing to guide us but reason will solve this worlds problems is essentially an article of faith. Almost humans have a tendency to devote themselves to a particular cause in order to derive a sense of solidarity or meaning, or else do so in the belief that the said cause will create a better world. Bertrand Russell defined fanaticism as believing one matter or cause to be pre-eminent among all others in one's life. I think to a large extent this is whats happening here with certain posters.
Now, I understand that in the USA secularists are under intensive pressure from bigots ignorant of everything but biblical learning. However, for the purposes of your cause don't you think your image is a little counter-productive, perhaps even hypocritical? This gung-ho attitude seems obnoxious to an outsider. In your disdain for theists and whomever else you decide to brand as 'irrational' you are in many respects mirroring the aloof attitude taken by religious fundamentalists. In many ways you are attempting to shove a message down unwilling throats and flaunt the superiority of your belief system over others. Take your the usage of your term 'mind disorder' in your site banner as an example. That implies that any who hold a religious belief do so because they are mentally unwell and are therefore inferior as human beings. Calling a person psychologically unstable simply because they hold a different opinion or think differently about a certain matter is pretty damn scary. If you're hoping to convince others they aren't going to respond very kindly to that kind of sentiment - imagine if you saw a site banner that read 'fighting to free humanity from the mind disorder known as atheism'. As I said, a little scary, and not very endearing. And yet given the history of human civilisation its arguably a claim with more weight behind it - assuming that we base what is 'natural' on what is the most prevalent.
Polite, intelligent and moderate debate is the best way of sorting through conflicting ideas and beliefs. Calmly explain your position, and the ellucidate reasoning behind it - don't try and force it on others. Respect is integral to this process. Try and show it to others even if it isn't reciprocrated. I guess what I'm trying to say is that despite the apparent sound reasoning and supportive evidence behind your beliefs, your attitude to others is something you really need to take into consideration. The last thing you want to do is adopt the attitude and approach of a hardcore evangelist - try not to fight fire with fire! Atheism may be very the metaphysical foundation upon which you choose to live your life, but don't let atheism itself become the focal point of it. Just like religion, socialism, fascism, patriotism etc. secularism can to some extent become an all-consuming ideology rather than merely an accepted truth. I'm interested to hear your thoughts, will check back later.
