And also it's important that they make clear it's unacceptable and take action: It's like bullying; people passively watching send the message that the behavior is socially permitted. People are hard wired to follow social norms. > they're going to have significant discrimination problems as long as people are discriminatory, i.e., basically forever. Discrimination isn't forever. Protestants and Catholics, not to mention Irish and Italians, and many others used to riot against each other in the U.S. When John F Kennedy, a Catholic, was elected President it was actually a big deal. Now nobody even notices when a Mormon runs. Look at discrimination against women, Jews, LGBTQ, and many others. It takes too long, but the history is very optimistic. I even hear that most American voters voted for a black man - twice - only a generation after he wouldn't have been allowed to even sleep in a hotel in much of the country. (Could he get an Airbnb room now, if he weren't recognized? I sure don't want to go back to those days.)
