My brother was a remarkable person -- a gifted preacher, a champion of education, and a powerful advocate for the rights of Blacks. If there was one event that angered my brother more than any other, it was the tragic demise of "Africville." No attempt was made to save that Halifax Black community.
I don't know how history was taught when you were in school, but in my school our teachers skipped over the chapter (yes, only a single chapter) on blacks in Canada and North America more generally. These omissions skew our view of the world and lead to erroneous assumptions.
