“People go funny in the head when talking about politics. The evolutionary reasons for this are so obvious as to be worth belaboring: In the ancestral environment, politics was a matter of life and death. And sex, and wealth, and allies, and reputation... When, today, you get into an argument about whether "we" ought to raise the minimum wage, you're executing adaptations for an ancestral environment where being on the wrong side of the argument could get you killed. Being on the right side of the argument could let you kill your hated rival![...]Politics is an extension of war by other means. Arguments are soldiers. Once you know which side you're on, you must support all arguments of that side, and attack all arguments that appear to favor the enemy side; otherwise it's like stabbing your soldiers in the back—providing aid and comfort to the enemy. People who would be level-headed about evenhandedly weighing all sides of an issue in their professional life as scientists, can suddenly turn into slogan-chanting zombies when there's a Blue or Green position on an issue.”

“No matter what side of the argument you are on, you always find people on your side that you wish were on the other.”

“You have to predict and examine and understand every argument the other side is going to throw at you. It's not about being the one who's right. It's about showing them why they're wrong.”

“You see, a conflict always begins with an issue - a difference of opinion, an argument. But by the time it turns into a war, the issue doesn't matter anymore, because now it's about one thing and one thing only: how much each side hates the other.”

“I'd never really had arguments like this before, arguments I couldn't understand properly, arguments where both sides were right and wrong all at the same time.”

“We all are learning, modifying, or destroying ideas all the time. Rapid destruction of your ideas when the time is right is one of the most valuable qualities you can acquire. You must force yourself to consider arguments on the other side.”
