It's as though this guy has missed the boat. He really doesn't have a clue what the concept of a "melting pot" is. (Being a Euro, this is understandable)
"So ready"??? Huh? This happened a generation or two ago. Hubby and I have German ancestors. We think of ourselves as Americans and really don't care where great-grandpa and great grandma came from.
When we eat ethnic food it's usually Mexican, Chinese or Italian. We just drink German.
Many Americans are lucky if they even get it right where their great grandparents are from. I think most American kids today have only the vaguest notion of which country their ancestors might have come from. I've heard people say 1/3 Irish, 1/3 German, 1/3 French or list more percentages than add up to one. For most of us, it really doesn't affect us one way or another if one ancestor came from Poland instead of Germany or Ireland or Italy. Who cares.
