Academics are some of the most political, vicious backstabbers of any group of people. They will work not only to disprove another person's theory, but to destroy the person. There are many examples of scientists being driven out of their field by the old gaurd protecting their work from new ideas, only to have the new ideas eventually proven correct, but too late for the original scientist who proposed the idea.
A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather its opponents eventually die, and a new generation grows up that is familiar with it. Max Planck
Absolutely true and my knowledge is first hand.
