Humanity needs to have a central interest that all groups can relate to. Most of human tensions across groups are born out of not understanding difference in expression. All our ideas come from observing the world, the most obvious central unifier. If our education is geared from this premise, we can learn the expression of the land we are born and also relate easier to the same expression from other places in different words. Different is not wrong (there is nothing wrong, only what we don’t understand and express our discomfort for, as in hate). It’s fine to have pride and love for where you come from, but it is also fine to learn why it is not really any better or worse than anywhere else, as it is all part of the same one planet.
Educate global, learn local.
