Life is not a sport. Life is not math. There is no final end goal and there is no right answer. Just because your truth does not match someone else's truth does not make either of you wrong. Life is not a zero sum game. If I am right, that does not make you wrong. If you are right, that does not make me wrong either. A jar of vinegar can sit in a cupboard beside a box of baking soda peacefully, and we can allow those who disagree with us to exist alongside us without reacting to them. There is nothing to prove. There is enough room in the world for all of us.
Love is wise; hatred is foolish. In this world, which is getting more and more closely interconnected, we have to learn to tolerate each other, we have to learn to put up with the fact that some people say things that we don't like. We can only live together in that way. But if we are to live together, and not die together, we must learn a kind of charity and a kind of tolerance, which is absolutely vital to the continuation of human life on this planet.
Do you know, the only people I can have a conversation with are the Jews? At least when they quote scripture at you they are not merely repeating something some priest has babbled in their ear. They have the great merit of disagreeing with nearly everything I say. In fact, they disagree with almost everything they say themselves. And most importantly, they don't think that shouting strengthens their argument.
It's okay to disagree with the thoughts or opinions expressed by other people. That doesn't give you the right to deny any sense they might make. Nor does it give you a right to accuse someone of poorly expressing their beliefs just because you don't like what they are saying. Learn to recognize good writing when you read it, even if it means overcoming your pride and opening your mind beyond what is comfortable.
Morality binds and blinds. This is not just something that happens to people on the other side. We all get sucked into tribal moral communities. We circle around sacred values and then share post hoc arguments about why we are so right and they are so wrong. We think the other side is blind to truth, reason, science, and common sense, but in fact everyone goes blind when talking about their sacred objects. If you want to understand another group, follow the sacredness. As a first step, think about the six moral foundations, and try to figure out which one or two are carrying the most weight in a particular controversy. And if you really want to open your mind, open your heart first. If you can have at least one friendly interaction with a member of the “other” group, you’ll find it far easier to listen to what they’re saying, and maybe even see a controversial issue in a new light. You may not agree, but you’ll probably shift from Manichaean disagreement to a more respectful and constructive yin-yang disagreement.
