Since we are a democracy those things should have been voted on by the American people. If the American people wanted slavery we should have had the right to keep it. If the American people want to keep blacks from marrying whites we should be allowed to do so. The majority rules (guided by Biblical principles obviously).

Women should not be voting anyway. They're too inclined to make choices based on emotional appeal and they're easily deceived. According to Biblical principle the male heads of household should run the community and the nation (and the church). Each home should be granted one vote, which the eldest male should cast.
