Thank you, Margaret, for backing up common sense with irrefutable logic. 
Making a group of children feel guilty because of the colour of their skin is racism, pure and simple. 
My children grew up "colour-blind" in a completely multicultural suburban neighbourhood and we knew all their friends and parents. There was simply no discussion about the colour of their skin and we still have contact with most of them through Facebook. The little girl next door was from an Egyptian muslim family and she has become a well-known author and public speaker. My son married a girl from the Chinese community and I now have two lovely multracial grandchildren.
The social justice warriors of today are sowing the seeds of hate and division. You cannot help the victims of one group by victimizing  another. The multicultural suburbs of the 1970s are being  replaced by single culture / religion communities that are recreating their homeland rather than integrating into Canada. This is the wrong path.
