Actually, Dobson's boycott has nothing to do with their corporate emblem.
It has to do with a local anti-gay ordinance that they worked to overthrow.
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.
Thanks for setting me straight on that story. I didn't know about the labor disputes at all.
