The incentive for you to share your beliefs is that if you will not lead, someone else, invariably less discerning, less principled, and less honest will. This used to be considered a fundamental precept of Western civilization and its legislators, popularly stated as "[t]hose who are too smart to engage in politics are punished by being governed by those who aren't."

The historiography of this period, if humans remain extant, will discover the causal link between the rise of New Atheism and the rise of intellectual cowardice that by necessity emerged shortly after the implicit social norms of Christianity were intentionally jettisoned.

Being willing to sacrifice, not to inflict violence but to actively suffer, for the truth that one witnesses is a fundamental predicate of Western civilization. Even the Christian heretics of the middle ages, willfully executed for their idiosyncratic beliefs, viewed this as a sacrosanct duty as a human being.

If a polity actively consents to the silencing of the individual's ability to testify to their truth for the sake of Mammon, state persecution, the possibility of being stoned by a crowd of True Believers, or any other exercise of temporal power, civilization, that is the ability of a group of diverse individuals to exist for a future commonweal, is impossible to maintain.

The honest and earnest among this and past generations have voluntarily silenced and removed themselves from the possibility of being spiritual and intellectual leaders. The only result that can come of this abdication of responsibility is not their own safety but the endangerment of everyone within that society.

If you will not lead, you will be led by those that aren't so fearful, so future-minded, or scrupulous. If you would pretend to be blind, you will be led by the blind. And if the blind lead the blind, both shall fall into the ditch.
