What’s happening today is not anything like the Ellis Island immigration in the old days.
My then-young Dad (3 years old), his older brother and older sister, and their mom & dad came through Ellis Island in 1927. My uncle was traumatized by the exam they gave him (age 7 at the time).
By the way, I don’t think we were “irradiating” major diseases at Ellis Island. But we did successfully eradicate them.
