The degree that someone is willing to make others uncomfortable by the things the say is equivalent to his/her commitment to truth. Without a willingness to incite discomfort, you do not have an ability to speak. And this is a dangerous thing, especially when summed across the masses. It threatens a necessary correlation between perception and reality.
Although there needs to be a nobler purpose to justify inciting discomfort in others. Those who flaunt their need for provocation are often bored and childish. The person who at first is reluctant to speak, because of their awareness of the pain their words inflict, is the citizen that’s needed to maintain health and stability in society.
