Majority opinion being wrong and unjust is not new. Our democratic history is littered with examples of majority opinions being not just wrong, but the very opposite of democracy when those opinions were shaped into laws.
Listen carefully to the volumes of promises and plans about to be delivered; hear what the politicians are saying. Think for yourself. And never forget that most of the great social changes in our lives have been brought about only when minority movements forced sheeplike majorities to listen.
