No, I think you do, I've seen enough of you posts to know that those words are far too difficult for you to use. Let's look at each of them and see if they apply.
Demagogy: political activity or practices that seek support by appealing to the desires and prejudices of ordinary people rather than by using rational argument.
Normal people understood that a man purposefully burning 16 elderly Americans while screaming 'Free Palestine' is terrorism. How does that fit the definition I so kindly supplied for you?
Stereotyping: a specific belief or assumption (thoughts) about individuals based solely on their membership in a group, regardless of their individual characteristics.
Huh, maybe it had something to do with the scumbag shooting a flame thrower at innocent people screaming terrorist propaganda. Not exactly what people with even a single brain cell left would call stereotyping. Nobody stereotyped the lunatic, they simply described him, his actions, and his words.
As I mentioned, I've seen your post, you're definitely too stupid to read and comprehend these definitions and you certainly don't understand how to use them. Maybe you should stick to a comment chain on CNN's website, where you can blend in with the rest of the dumbass drones.
