[Alan Chapman]

...The ones that supported slavery didn't view blacks as equal humans. However, the witchcraft and sodomy laws applied to everyone. And the very authors of the USC supported those state laws.

I was merely following your line of reasoning to its logical conclusion.

You said, "...the founders supported state laws that prohibited witchcraft, and sodomy..."

Therefore what? Therefore we should support something because the founders supported it? That isn't an argument. It is a fallacy known as Argumentum ad Verecundiam.

[Jhoffa_]

Therefore we should support something because the founders supported it?

If it's the States right's to self determination.. then certainly we should..

[Texaggie79]

Therefore it would stand to reason that those laws where Constitutional, when the very authors of it supported them.

I submit that they didn't view blacks as equal humans, therefore slavery was constitutional. Their mistake was in that belief. What say you to their mistake in thinking States can prohibit and outlaw certain activity and property?
