I'll just cut you off there. This is an example of you trying to make this story more palatable to yourself by making up fictional details that have not been provided in the story. If you can back up these claims with evidence, I'll be happy to discuss whether or not they change anything.
I'm not trying to make it more palatable by making things up. My point is, according to Sharia law, there should be four witnesses. For all I know, they might have kept that detail out. Sure. I'm talking about what one would expect would be in a book taught to Muslims.
My personal view? So long as they aren't encouraging people to go out and take the law into their own hands, and simply stating what some scholars think, it shouldn't be classified under a hate crime. However, it should be restricted to, say, teenagers, who don't soak up everything they hear like children do. In this specific case, though, it seems the way they presented it, and some of the fictional ideas they added in (sounded like they may have taken the Protocols for truth), I cannot agree with.
Take talking about how skinheads believe in the purity of the White race and all that. If you are in a Social Studies class and the topic is about, say, racism, or European movements, or something like that, I don't think it would be a hate crime to mention their views. However, if the teacher starts telling students, "You know, those blacks are like animals," that's crossing the line, and that would be a hate crime.
I hope my position's clearer.
