>>117428210Yes it was believed that Ham, one of the sons of Noah married a black woman thus allowing the black race to be perpetuated. They thought this because supposedly the Cannanites where decended of Ham and they were supposed to be a dark tribe.
(Their dark skin was supposed to be the Mark Of Cain or something like that.)
Anyway, when Noah got drunk and passed out naked after the flood, Ham was the son who actually called his dad out on it and Noah cursed Ham to "be a servant to his brethren".
And that is how some Christians justified the slavery of Africans.
(And later how Mormons justified withholding many church privileges to black memebers).
That dude in the pamphlet is actually saying that calling blacks descendants of Ham is wrong because if they were then that would mean that blacks are actually part of the human family, which he contends they are not.
(You probably already figured out that last part on your own, just felt the need to spell it out.)
