And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation; Acts 17:26
1) Ham was named at birth, long before Noah's
curse.
2) The curse was pronounced on Ham's child Canaan, not Ham
himself.
The Canaanites were a pale skinned race!
.....support for slavery’s role in heightening racism comes from 
comparing
the different social outcomes in the U.S. and Brazil.
In the U.S. during the
era of slavery, there was an emphasis that was largely lacking in
Brazil: that all people, being descended from Adam, are created in God’s
image. It means they are all intrinsically equal, one human family,
despite all the variety and cultural differences, as the Declaration of
Independence said.
*So in the U.S., there was a pressure to concoct
schemes to make the enslaved group less human—but not in Brazil. This is
one important reason why, after slavery was abolished, Brazil had far
fewer social problems involving black-white racism than the U.S.
It also explains why such Biblically untenable (though allegedly 
Biblical) notions as ‘pre-Adamite races’, and ‘the curse of Ham led to black skin’ arose and/or were prevalent in the white culture of the USA, yet not that of Brazil.
In a society with more Biblical leanings, the anti-racist and
anti-slavery implications of the straightforward history of humanity in
Genesis had to be neutralized.
Like today’s theistic evolution
compromises, these ideas were not driven by what the Bible said, but by
the outside ideas prevalent in the society, which were then read into the Bible.
.... the evidence indicates that throughout history, people enslaved 
others
whenever they had the means and opportunity, regardless of their ‘race’.
Black people were captured by other black people for sale to
non-African markets. Huge numbers of ‘white’ Europeans were enslaved by
both whites and non-whites. The word ‘slave’ itself 
comes from one of
those heavily enslaved white races, the Slavs. In fact, the Barbary
coast pirates of North Africa had such a thriving and entrenched white
slave trade in the early 1800s that it caused the US to send military
forces into battle there, inspiring the famous Marine Hymn line, ‘To the
Shores of Tripoli’." CMI
