Yep, that’s another survival tactic, it served us well when we were roaming and searching for places we could live and eat. Not so much now when we all are supposed to have our own wants and futures and we can get packaged meat at the local grocery store.

The trick is going to always be for our species to figure out ways to get people to use these survival impulses in ways that help us as a community. And I don’t know how we’re going to do that at all. Fear and anger are much stronger emotions than charity and compassion for strangers who look or talk different than us.
