A society with a multiplicity of Gods brought us tolerance – not just
religious tolerance, but *intellectual* tolerance. Monotheism killed
philosophy, burned down the libraries, and brought us the Dark Ages.
The title is meant to convey/cast doubt upon polytheism. But as you read the comic, you’ll realize (perhaps) that it not only applies to polytheism, since it can be extended to accommodate theism as well.
I agree that religion can bring along with it intellectual tolerance, or as I prefer to coin it, suppressing the faculty of reasoning or even suspending skeptical inquiry.
