People are not creatures of logic, but instead creatures of emotions bristling with prejudice and motivated by pride and vanity

Quoted from Dale Carnagie. Why do you think talk show hosts and media figures do what they do? Ever notice how almost nobody ever uses purely logic and deductions when trying to convince people of something? Instead they try to play on peoples' emotions, trying to inspire anger or frustration. It's what works, and it results in a bunch of people screaming for the sake of screaming (see below). What more is there to say???
