:"you shall have no other God,s before me"
Note that God did NOT say, "you shall have NO other Gods." NO! God said, "you shall have no other Gods BEFORE me", i.e. "I am the King Shit God. Any other gods are secondary."
Ergo, it's not forbidden to have other gods, but keep them behind (not BEFORE) BiblleGod.
It's all so simple when you read it and understand it like it is stated, not like people who say it means something other than what was actually stated.
