I'm 27 yo, IT specialist, live in Croatia, and I'm an atheist. On the Dawkins atheism scale I would probably rate 6.9999 ad infinitum.
I was raised in a Catholic home but my parents very rarely attended Church and we never really discussed God. I probably became atheistic when I concluded that there is no Santa Claus and no Easter Bunny. The fact that I practiced reading from a general Encyclopedia (with great pictures and descriptions) and illustrated Greek mythology tales when I was about 5 probably helped me to develop the ability to discern fantasy from reality. That didn't help much in school because I didn't want to attend the Catholic religious education class (Catechism). After my first three years in primary school I managed to argue my way out of it by constantly challenging the nun that held the class to provide evidence of God's existence, asking about the other planets in our solar system and speaking about Greek gods and why shouldn't we believe in them. I was about 9 or 10 years old at that time and I didn't respond well to threats of eternal damnation if I continue to 'test God's will'. So I usually spent the time sitting in the hallway for the first 8 years of my education waiting for my classmates to finish their indoctrination sessions.
In my teens and when I started attending high school (and was the only one that had Ethics class instead of Catechism - was alone with the teacher) I had a lot of time for serious reading because I had to wait for a train for several hours each day. I read Aristotle, Plato, Kant, Nietzsche, books about logic and then went on to religious texts. I've read the Bible two times, skimmed through Torah and the Qur'an, read the Baghavad Gita, the Book of Dao, started reading about the mahayana and Ch'an and then I went through my Zen phase which lasted a few years by reading a lot of Daisetz Teitaro Suzuki and later some older texts.
During my time at the University of Electrical Engineering and Computing I had math and physics classes so I fell in love with cosmology, astronomy, astrophysics and quantum physics. That will probably be my life-long obsession.
Apart from my interest in religion and the way it influences society and rational thought, I'm also an amateur astronomer, avid reader of Sci-Fi and Fantasy literature, TED.com Translator (current fancy) and a Richard Dawkins and Michael Shermer fan ('militant' atheist + skeptic). :)
Since I probably overdid the introduction a bit (on vacation - typing from the beach) :) I'm going to conclude with saying that I'm looking forward to being a part of this great community and hopefully a contributing member.
