Truth Time!
The upside down cross is not a Satanic symbol. I'm sorry to disappoint you, but the upside down cross is Peter's cross. Peter was crucified and didn't find himself worthy of even dying the way Jesus did. He was crucified upside-down, hence the upside-down "Satanic" cross.
Not everything that is different is bad. As much as I believe with every fiber of my being that the Clintons are, in fact, of the devil, the inverted cross is no such indication.
