If a child from an Amazonian hunter-gatherer tribe comes to Boston, is raised in Boston, that child will be indistinguishable in language capacities from my children growing up here, and vice versa.
Growing up in the place I did I never was aware of any other option but to question everything.
When I was growing up in the 1930s and '40s anti-Semitism was rampant. It wasn't like Nazi Germany but it was pretty serious - it was part of life.
