Simple fact of the matter is that you KNOW the most used, and dangerous, guns will not be banned. So, because that's a lost cause, you want something to feel good about. Very few people own AW, very few people want to own AW and very few people will get an AW. So, much like "Tax the rich!", get behind an idea that doesn't affect very many people, and has little to no effect of the perceived problem, and go after that.
There's a six letter word for what you want.
Stupid.
