In 1904, Mark Twain's Notebook said "Whenever you find yourself on the side of the majority, it is time to pause and reflect."
In 1835 Alexis de Tocquevile published Democracy in America in which he expressed concerns about democracy in America. 
He feared that public opinion would become an all-powerful, tyrannical force.
I ask you, who controls public opinion?
 He stated the "the majority represses not only all contest, but all controversy. I know no country in which there is so little true independence of mind and freedom of discussion as America.
Majority rules!
