Religious or secular, fundamentalism is not unique to any particular political persuasion. To those in narrow-minded pursuit of ideological purity, disagreement is tantamount to treason and punishable by censure, ostracism, or cancellation.

Passionately argued, coolly critical, irreverently humorous, The Right to Be Wrong is a vigorous defence of independent thinking in an increasingly conformist world, which dares to ask: What do we lose if we lose the freedom to disagree?
