While I don't have a problem with this, it is dishonest to equate Canada to the plantation slave states. Slavery was made illegal decades before Canada became a country. The overwhelming number of slave-owners in pre-Canada were aboriginal. We know very little about blacks in pre-Canada because there was so few of them. Some were slaves but SJWs assume all were. As almost all black families immigrated well after slavery, a black in Canada is a thousand times more likely to have a black slaver in his background than a black who was a slave in pre-Canada.
