It is precisely thinking, conversation, and debate that help us learn, understand, and evolve. It is one of those big things that distinguishes humans from animals. Without debate, we would become unsocial, docile, and ignorant beings. Debate is also one of the kingpins of democracy. It is what encourages questioning, healthy cynicism, and dissent. It is what helps maintain a relative of balance of power and influence. Once you accept the idea that you should just shut up and accept the commonly accepted information or view, then we’re all doomed. So long as we are thinking, conversing, and debating, we’re not abusing or killing each other… Well, hopefully.
