It is definitely true that we all hold on to our own irrational beliefs - that applies to even the most seasoned skeptic. I once believed that if I could simply show people the evidence, they'd change their mind (that's pretty crazy!) - and I still try, to this day, to present the evidence to people in hopes of them seeing the light.
The point of this posting is more out of frustration - simply because you're an atheist doesn't mean we're anything alike. On top of that, being an atheist doesn't make you a skeptic. It makes you an atheist - and as they say, atheism is nothing to believe in. It's a non-belief - we simply share a lack of something.
As a fairly outspoken atheist in my social circles, I'm often confronted by "believers" or "friended" by other atheists and I'll, shamefully, admit that I'm not, often, impressed by the beliefs (or non-belief, in a sense) of some atheists. And, for that, I must explain.
Atheism, as I've mentioned many times is a non-belief - a lack of belief - and hardly suggests a true commonality. With atheism, there are no dogmatic beliefs, there is no doctrine and there are no core elements. We simply don't believe that a god or gods exist.
I would like to associate "atheism" with the idea of real "truth" and rational thought. I would like it to be the hallmark of properly applied skepticism but it is far from that.
The sad reality is that I know (too many) atheists who are not at all skeptical - some believe in homeopathy and naturopathy and others in psychics and other forms of the paranormal. You are "my kind" of atheist when you've reasoned yourself into non-belief and you use reason as your primary method of navigating through the non-sense. Mind you, as my wife can tell you, "my kind" of atheist probably can seem "cold" or to lack feelings at times. Oh well, sometimes the truth isn't all that pleasant but I'd rather the truth than some false sense of comfort.
Whatever other beliefs (or non-beliefs) that you hold, if they make you vote irrationally, spread falsities and lies and distort science and medicine out of sheer ignorance, I'm probably going to suggest to you that you're not a skeptic or a "reasonable" atheist. Because you can see the absurdity of sky-fairy belief does not make you a rational thinker or an expert at discerning the "truth".
No matter what it is that you accept or "believe", what is it that leads you to "believe" that? If you don't have reason to believe something, speaking about it with certainty makes you a fool - no matter what god/gods you do or don't believe in.
Just think - it'll do us all a whole lot of good.
