Does Atheism have a Generally accepted Symbol (and do we need one?)

[FatAndFaithless]

But it's also a reason why politically, our voice remains unheard, even though we are a non-trivial portion of the population.

But there is no political voice other than not wanting religion mixed into political affairs. Otherwise there are as many political views as there are atheists. I wouldn't even piss on Ayn Rand if she was on fire, but others might, while still others may even try to resuscitate her.

And as such, I don't feel a need to form a 'team' logo to identify myself with them, I feel absolutely no need to.

If people want to form a club or forum or group and call it an atheist group and make icons and hats and bumper stickers, all the power to them. But trying to have one "real" universal symbol would just rub a lot of atheists (pretty much every one I know personally and especially the ones with whom I disagree with politically) the wrong way.
