To talk to a political bully?

In politics, we tend to forget that to be principled is different from being dogmatic.

A principled leader knows the goal posts, keeps in mind the values that must be respected, and, because of that, he or she can engage in a negotiation. The dogmatic one is just a bully, a political ruffian. He can only operate from what he sees as a position of force, even when such position is no more than an illusion. The bully lives in a fantasy world and sees himself at the centre of it. To engage in a dialogue with such a person is a lost of time, unless it is just a tactical move to regain the initiative.
