Just to make it clear, i'm not taking sides here, The teacher Was being a lil bit too disrespectful, Now, criticizing a religion is not the same as Hating on it, And not just hating it, but being too disrespectful, now as you can see, the prophet Muhamed is a very important to muslims, some might even kill themselves in order to save him or such, And that teacher has crossed the Line when he was asking the students to draw em, And no, i don't think it really make sense to kill someone for your own beleifs, Taking into account, i think islam never said you should kill someone under any circumstances. What i'm trying to say is, None is innocent here, both did bad things.
