Actually, Dobson's boycott has nothing to do with their corporate emblem.
It has to do with a local Cincinnati anti-gay ordinance that they worked to overthrow...perhaps some of the soap opera influence, too....
The stars and moons symbol comes from the 1800's when P&G was formed and is simply a man and the moon picture that was faddish at the time. I grew up in a P&G family, and then worked there myself for a while. We've known that story to be bogus for years.
The story from fifteen or 20 years ago is starting to come back to me now, back then, it (the symbol) was attributed to some Satanic cult symbol. Completely unfounded and basically the story died on its own.
