Your misapprehension is that children's first encounter with Racism is from Elmo.

Racist parents exist and might be absentee enough to let their child grow up watching Sesame Street.

Cognitive bias is subtle and insidious and children are not immunized in ignorance.

To quote Proverbs: "Train up a child in the way he should go: and when he is old, he will not depart from it."
