When you think about Tom Brokaw comment about assimilation?
He didn't address the assimilation they need to face.

Who created Jim Crow?
Who segregated Asian American during the second war.
What group tried to eliminate a mass Jewish population?

Presently, still using fear tactics about others because they know this group fears others.
