(Sorry for wall of text)
I was Atheist, but after thinking about it for a while, I realised being Atheist is just as ridiculous as being Theist (from a logical perspective)
As I understand it, 'God' does not operate within the laws of science. This is a perfectly reasonable thing to say, that 'God' does not comply with the laws of science because he is outside the scope of our Universe. However, assuming this no scientific experiment can possibly be conducted to prove or disprove 'God'. This means the scientific method cannot be applied therefore rendering the entire subject outside of science. Effectively then, this reduces the entire argument to a metaphysical one. When considering metaphysics, anything is possible. It is just as likely that there is a 'God' as there is any other concept or idea outside of the Universe. This means that taking the Atheistic point of view, that there isn't a 'God', is just as unjustifiable as saying there is one. So in a sense, all arguments against Theists apply equally to Atheists. This makes the only logical and reasonable standpoint to be that of an Agnostic.
This kind of Agnosticism is not that you can't make up your mind, but that you accept that making up your mind would be an illogical thing to do (unless evidence came to light that the situation was no longer metaphysical).
Via similar logic, I believe it is still well within reason to question events that Theists claim to have taken place within the Universe and therefore within the domain of science. For example, Creationists. They are fully entitled to believe in a 'God', no one can say otherwise. They can't say though that evolution is a complete lie based on their Theistic belief. This is something that can be proven and it is not a question of faith. I don't want to enter a debate on this topic though as it isn't worth my (or anyone's) time. Familiarise yourself fully with the topic before giving your opinion, otherwise it is a worthless one.
In saying this, I am not criticising either Athiests or Theists. They are perfectly entitled to have an opinion, even if it is not founded in logic. Like if someone thought the best colour was red. I respect your opinion, but I still believe the argument to be a pointless one. I must finally emphasise that I still heavily criticise many Religious Organisations in the world. Religions can not claim absolute morality as part of their religion and should not exploit masses of people on the bases of their beliefs (this is the organisation, not necessarily the members).
I believe that many Athiests mean this when they say they are Athiest. I don't know if there is a word for this standpoint specifically, but one should certainly be thought up if not.
