Atheism Atheism is fundamentally a reaction to theism and is overwhelming expressed as a disbelief of theist claims. Atheist opinions will vary from absolute certainty that gods do not exist through various degrees of uncertainty to simple skepticsm. Typically when asked, an atheist will say they do not believe in the existence of gods. Many atheists will leave open the possibility that gods might exist providing appropriate evidence is provided according to Wiki. ------ yes they say atheism is a reaction to theism, the opposite of theism, but during the pro-anti debates here on sciforums, I think we need to discuss the difference between an atheist and an anti-theist, to me an atheist is just someone who does not believe in any God or Gods (and they have no desire to promote their own opinions), an anti-theist is a person who is very verbal and active in their opinion that God does not exist and goes so far as to try to 'convert' a theist to atheism atheist often have no experience with religion(never joined church), anti-theist often have had bad experiences with religion (exchristians). so my opinion is we should include the term 'Anti-theist' in those stickied defintitions. thoughts? opinions?
