Oh I'm not even offended. I know some Satanists are sick (ones who harm animals and children), but the actual book says to not harm anyone. There are a lot of sick Satanists, Muslims, Christians, etc. who go against the book they believe in a lot of them are nice people.
I don't agree with this specific group putting books in classrooms (if anything they should ask the school to take them out), but it's not like they threatened to burn their school alive if they didn't take their coloring books.
