do you use exorcism on atheist, Muslim or Hindu ghosts?

not sure about Muslim or Hindu, but here's the procedure for exorcing the atheist demon:

1. Get $1000 in cash

2. Make sure you are alone with the atheist -- if there are other people nearby demon will go defensive and it will not work

3. Wave the money in front of atheist's face and read aloud the following prayer: "I'll give you thousand dollars if you become a Christian"

4. Once the atheist accepts the money, the demon will loose control over him, and he will join you for a church service

5. You cannot permanently detach the demon, in fact you might have to repeat the procedure monthly.

Why is exorcism only necessary on christians?

Answer: Its all bull. Caused by psychosis.

the atheist demon would be called the antiChrist Muslim & hindu would be called religous demons (so yes)

Find me a ghost, then we'll talk about that other stuff.
