It seems as though most of the people who got satanism did not read up on it at all - it's not what you think, look into it a bit. Since paganism was not on this list, I have to agree with my score based on the choices available...

Satanism 100%
Agnosticism 65%
Islam 45%
Hinduism45%
Atheism 35%
Judaism 30%
Christianity 20%
