People as individuals, one-on-one, can be kind, decent, tolerant, etc. It's "tribes" -- groups, organizations, nations -- that can be problematic. They are easily swayed and group-think is a hallmark. Think about France following WWII. America was the driving force that released that country from Nazi oppression. National gratitude lasted until De Galle came into power. You could still find kind treatment of Americans in the outlying regions of France, but in the major cities, forget it. Even so, a dear friend of mine for many years was French and from Paris. So again, individuals are fine. Groups? Not so trustworthy.
