There is a US State Department site that explains this concept, for those who have a problem grasping it, from a document called Principles of Democracy.
Majority rule is a means for organizing government and deciding public issues; it is not another road to oppression. Just as no self-appointed group has the right to oppress others, so no majority, even in a democracy, should take away the basic rights and freedoms of a minority group or individual.The California Supreme Court has made a decision that these Principles of Democracy do not apply in our state. They have upheld the tyranny of the majority and crushed the rights of the minority. They have failed in their constitutional role to protect us. And this was spelled out explicitly in Justice Moreno's withering dissent.
So, they have set a dangerous precedent that ANYONE'S rights are subject to modification by majority vote-- ANYONE. That means left-handed people, redheads, Mormons, the disabled, and any other definable group can have their rights legitimately eliminated by the mob.
BUT: Prop8 supporters did not win what they think they did. Because the court did say clearly that all this applies to is the term "marriage". The actual rights-and-privileges of marriage are still to be available to gay and lesbian folk, just not the name--that is an explicit statement that "whatever it is called" is a marriage in ALL but name. If the H8ers wanted to eliminate all the benefits of marriage from gays, then Prop8 would have been a revision, and unqualified. To qualify as an amendment, the effect of Prop8 must be limited to the name "marriage".
Think about it. This means that there must be state forms that include the DP'd folks: "Single or Married/unioned". This means that kids will learn that there are marriages and DPs in school, and yes, teacher may invite them to her wedding (because they didn't take the name wedding, just the name "marriage"). This means that under law, GLBT "whatever you call its" WILL be treated the same as "marriage" .
Prop8 is still wrong, of course, and the court did fail. We must over turn it. But I wonder how long it takes The Forces of H8 to figure out that they didn't really succeed doing what they thought they were doing.
As the expression goes, the arc of history may be long, but it bends towards justice.
