Democracies are not the dictatorships of majorities. In other words, our system is far more than doing what the majority wants.
In democracies, all residents have certain basic rights that cannot be violated regardless of what the majority thinks. (See the declaration of human rights for more information)
For example, there may be sexual acts that two consenting adults do that majority finds immoral. Should democracies be able to ban those acts?
What if, at some point, the majority finds Christianity or atheism immoral?
In a healthy democracy, the executive and legislative branches are democratic, however, to protect the minority judicial branch is independent.
