If you don't understand other people's behaviour, you have different perspectives.
If your president want to bomb another country to secure resource supply chain, you have different perspectives. Whatever. I'm not saying you or your wife, your neighbours or your president is right or wrong. All I'm saying is the source of conflicts is always based on the fact that both of your eyes transmit different stimulus and information to process to your brain, resulting in a different perspective on life itself. Religion, technology, finances, family, sexuality, politics, economics, war, meaning of life, human interference with nature, climate changes, capitalism, community-driven neighbourhood, simple living, car-oriented and designed cities, pipelines getting built, GMO food, social media bias, indigenous peoples accross the history, the holocaust, the Olympics, vaccine, coup d'État, social equity, generational equity, aborption, and so on. My opinion is just one amongst others. What can distinct yours is your tolerance toward other opinions. Don't surround yourself by like-minded people, find open-minded people to expand your views.
