So there is actually a valid critisism of Russel's teapot, or toaster in this case, that there could be a detectable causality that put the object in orbit even if the object itself cannot be observed (such as a rocket to deliver it). However, this (minor) flaw in a popularized analogy does nothing to reject what the analogy represents: A stupid idea that cannot really be falsified, even though it is false (see what I did there?).
Atheist do not carry any belief in not believing (this even sounds stupid). We simply have come to the conclusion that there is no basis for believing in any particular denomination, nor some unspecific general one for that matter.
Yeah, this is not a nazi bar.
