It'll never happen. I don't mean "gay marriage will never happen" kind of never, but Never, Ever. People under 15-16 years of age are simply incapable of consent. Gays getting married is at the very least an act between two consenting adults. Marrying a 10-year-old, or your pet parakeet, is not.

They're way ahead of you. It's the U.S. that's falling behind.
Give them marrage, and all ther desires are up next. Does NAMBLA ring a bell?
