Arn't Satanism and Christianity the same thing?

I think so that it is just a different God I'm mean think about it seriously think about it Satin and God are the Gods of Christianity Satanism is just the warship of Lucifer rather than God

( and I am a Christian any death threats will be reported)

Yes because it all comes out of the same fictional story book.

They are opposite sides of the same coin. You can't have one without the other.

Reverse Christianity and Christianity are two sides of the coin, yes. But Satanism doesn't worship Satan. I don't know why they decided to call themselves it, might be shock value, but I promise you, the VAST majority of Satanists do not worship Satan, in fact they're mostly atheistic.

Actually no. Get it from the horse's mouth:

All religions are based on a fairy tale of some kind. Those 2 are no different.

And as far as gods are concerned....No gods had anything to do with creating religions or inspiring them or no thin. Religions are all man made.

Not quite. Satan is not a God of Christianity. He was an angel named Lucifer who thought he was better than God, so to speak.

"Satanism is just the warship of Lucifer rather than God"

Thats one form of satanism... or so they call it.

Real satanism the kind recognized by the u.s. government as a real religion and not a cult has a different view.

The people you call Satanist's here in your question I call devil worshipers. They offend me horribly so, since they give me and others who follow the same path a bad name.

That argument could be made for the god of the Old Testament?but how is Jesus anything like Satan?

Basically both are same,
because,fundamentally or essentially there is NO difference between 'Satanism' and 'Theism'.

You couldn't possibly be a Christian, and have believes in other Gods. If no one has ever told you that. That as which you Speak of is also blasphemy!

My Satanism is based on Satan from the Kabbalah Thus not based on christian mythology and predates christian mythology by at least 1,000 years.
There are those Satanists we refer to as reverse Christians and yes in reality they are merely a mutated form of Christianity. If you are interested in my Satanism the manifesto is at http://www.sosatan.org
