OMG you couldn’t be more wrong!!!  Our son has spent 5 years in North Carolina as an undergrad and now a grad student.  In that time he has had 5 black room mates/fraternity brothers and many favoured professors who are black.  The only reason we know this is because we met them face to face.  They were NEVER described as such to us.  We taught our kids to be colour blind and are proud of the result.
