Is it hypocritical to manufacture products based on wrong ideas?

I work in CNC manufacturing (computer numerical control), and I recently purchased one of our machines in order to start a side business as a craftsman. Many immediate family members, for instance, would be interested in personalized home furniture goods like wall hangings, picture frames, jewelry boxes, and so on. Items with a Christian theme -- like a cross with a Bible verse -- are easy to make, customizable, and sell widely and well. Given that I'm an atheist, would manufacturing such goods be hypocritical? But what about other religious imagery, such as an engraved picture of the god Aries sleeping with Aphrodite and being caught her husband Hephaestus? After all, Greek mythology endorsed self-sacrifice, which I oppose. Also, what of historically-relevant symbols flags for Great Britain and Nazi Germany on a game board? I would refuse to print something like an ISIL flag but that seems different. So do these symbols have some intrinsic meaning that I would be promoting if I were to create them? Or are they merely given meaning by particular people in particular contexts, such that my producing and selling them isn't of any moral significance?
