Judging from your comment, you thoroughly misunderstand the textbooks you read. It used to be that the first task of a student was to learn how to advance a well-posed argument. Now, it appears, all you need to do is name-calling.
You on the other hand, instead of offering a difference of opinion and stating the reasons for that opinion, completely ignore the "advancing of a well posed argument" structure you rudely demand from him.
If any textbook you have "understood" has lead you to believe that name calling is a slur when its accurate and honest, then I am sad that you have not recieved the education that you should have.
Name calling, if true, and accurate, and honest, is proper.
Alan Blinder, while being a nice guy, is an idiot. His textbook was a joke littered with errors (not typo's either, not opinion biases, just errors).
I am like the preacher in church, telling the truth and it hurts.
