its more of a feeling of hope that I'm clinging too.
I also have some understanding why that person could not see those simple facts that blew a huge hole in her reasoning and why that person's beliefs (and all of ours) won't change anytime soon.
Quotes from. moral psychologist J. Haidt. (FWIW, he tries to understand why we are divided in order to bring us together. It's only through cooperation that we will survive).
"Morality binds and blinds. It binds us into teams … but thereby makes us go blind to objective reality."
"If you think that moral reasoning is something we do to figure out the truth, you’ll be constantly frustrated by how foolish, biased, and illogical people become when they disagree with you. But if you think about moral reasoning as a skill we humans evolved to further our social agendas—to justify our own actions and to defend the teams we belong to—then things will make a lot more sense."
"But the most important lesson I have learned in my twenty years or research on morality is that nearly all people are morally motivated. Selfishness is a powerful force, particularly in the decisions of individuals, but whenever groups of people come together to make a sustained effort to change the world, you can bet that they are pursuing a vision of virtue, justice, or sacredness."
