Hidden racial landmines or kids respond to incentives

From Betsy's Page "Two kids got suspended for using the word 'noose' because a black student said that he found it offensive. They weren't talking about nooses to lynch black people, but a noose to tie a knot."

If white kids can get in trouble for saying the wrong words around black children and the white kids don't know which words they have to avoid, then many white children will respond by simply avoiding all contact with black children. Political correctness, in this way, can foster racial segregation.
