Five nations have it completely and absolutely right (pun intended). Marriage equality is a secular definition. The city clerk's office says Marriage Licenses and not Civil Union Contracts.

Marriage Equality requires the need for one definition where two human beings, of opposite or same sex, contract to marry each other and often decide to raise families. That is the definition of thirty one years, four years of legal marriage not recognized in my nation, and a five year old son together.

Why does anyone expect us to take permanent second tier rights and privileges. Separate but equal is blatant bigotry.
I will accept a civil union contract if every heterosexual surrenders their marriage licenses and certificates and gets one too..... No takers, I thought so...
