I rather enjoy the way they stick it to the religutards. Their mere existence really pisses off the holy-rollers. I like them strictly for the entertainment value they provide.

Deities and demons are all pretend. Id suggest getting a productive hobby; play an instrument, volunteer at a school or nursing home, read Cosmology books, take art classes or just draw, tutor neighbor kids, walk neighbors' dogs .....etc.

Blennon has an in depth explanation here with all the political in and outs that covers Satanism very well. My take on it is much more simple.
Religious trolls might ask if I believe in Satan. My standard reply is "of course not" because I found god and the devil coming out of the same book.
