everyone's opinions on every subject are equal.
I rather believe democracy is the equality in rights. Not the assumption to equality of one's intellect or alignation of ideals with what is best. And a system to avoid domination by those who feel their ideals are superiour as the "stupid uneducated populus".
In a multi-party system you do end up, sortof, with a more colored government with different ideals in a representation of ideals. (Christian, Liberal, Environmentalists, Extreme Right, Socialist, Chauvenists, ...) representing or a history loyalty of ideals ("my father used to vote for...") or protest votes ("the larger party did not deliver") or actual informed votes ("these guys are the closest to my ideals").
