Amendment 43: Marriage - I'm voting against defining marriage as only a union between a man and a woman. It shouldn't matter if it's two men, two women or a man and a woman as long as all parties involved are consenting adults.
The problem with Admendment 43 is that the term Marriage has been defined and historically used for thousands of years as the union between man and woman, e.g. two physically different sexes. And because of that it has been embedded into not only secular documents but non-secular and legal as well. That assumption and perspective is deeply buried and intertwined such that it includes both physical sexes male and female.

Based upon that, my feeling is leave the term Marriage as it is and if the same-sex crowd want to have an equivalent term then more power to them but pick a different label than Marriage. If you use the same term then you open yourself up to inheriting a non-sensical perspective since some of the inherent description and implied rules are no longer applicable or at best are incorrect. To that end I suggest that rather than rewriting and inhereting the non-sensical parts of the marriage definition to simply create a new one designed for same-sex unions.
