Your logic is that of a flat Earther. Everyone believes the Earth is flat, therefore it is flat.
The majority once thought that slavery was good. The majority once thought it was OK to ban alcohol. The majority once thought that the earth was flat. Majority does not always equal "right".
I don't know if you can provide some documentation as to the validity of your statements 'the majority once though that slavery was good, wanted to ban alcohol, thought the world was flat'. I think you've taken liberty with the truth just to present what you believe to be reality today.
In the official declaration of the causes of their secession in December 1860, South Carolina’s delegates cited “an increasing hostility on the part of the non-slaveholding States to the institution of slavery.” According to them, the Northern interference with the return of fugitive slaves was violating their constitutional obligations; they also complained that some states in New England tolerated abolitionist societies and allowed black men to vote.
So no, the majority did not believe that slavery was good.
By 'the majority wanted to ban alcohol', I assume you're talking about prohibition and again, that's not true. The Woman's Christian Temperance Union succeeded in enacting local prohibition laws, not the majority. The temperance movement had popularized the belief that alcohol was the major cause of most personal and social problems and prohibition was seen as the solution. Special interest groups and lobbyists aren't a new phenomenon, and these 'good Christians' had the money to pay lobbyists and get the bill passed. National prohibition of alcohol (1920-33)—the “noble experiment”—was undertaken to reduce crime and corruption, solve social problems, reduce the tax burden created by prisons and poorhouses, and improve health and hygiene in America. This was not the will of the majority and was a complete failure. Even two presidents Wilson and Harding used to 'acquire' bootlegged whiskey.
Your last statement about the majority believed the world was flat. That may have been true of the majority in the days of Homer or Thales. President Barack Obama recently expressed impatience with the persistent objections put forward by climate change deniers by saying: “We don’t have time for a meeting of the Flat Earth Society.” It's used as an idiom for 'don't be an idiot'. The real Flat Earth Society issued a statement in support the hypothesis of anthropogenic climate change.
I defend the legitimacy of my statement,
majority rules. The Civil War ended slavery, the Prohibition Act was repealed, and it's been proven the Earth is round.
