If Atheists have a God, the way many believers insist we have, it isn’t science. The God of atheists is Truth (or Reality, or the Universe, depending on how you want to spin it.) Science, reason and logic are only the means of finding the Truth, but they’re also the only means we’ve found that work.
We are constantly appalled at the things that people want to slap the label of “Truth” on. Time and again we find people declaring something to be Truth on the flimsiest of pretexts. A reference to a holy work, or some revelation in the distant past or some deep inner feeling.
Yes, we know that there are many arguments to be had. Many religions have theology that is internally consistent, and many have theology that is quite beautiful. But when you hold them up to the light of Reality, it’s hard not to feel that your looking at some fancy decoration painted on a stick.
And so the temptation is always there to take up the hammer and join in the long tradition of idol smashing.
