I make this point on every one of these threads and it always holds true.
When Yuropoors visit or see America in the news they predominantly see New York and Los Angeles. Le 56% face is partly true in that people in urban centers and states with large Hispanic populations will possess large numbers of Mongrels.
It does not mean that 56% of white Americans have mixed ancestry. New England, the Rockies, cascadia and the Midwest are all monolithically white.
This meme is particularly ironic when Brazilians of Aegentinians use it- countries way more mixed than we are
