Unless unnatural means are used, procreation between man and woman is the only way that the human race can survive.  With very few exceptions throughout nature, a male and female are required for the propagation of that species. For 1000’s of years and in nearly all cultures, the formalisation of the partnership between a man and woman for the purpose of procreation, has been a marriage ceremony of some description, be it a religious or non religious ceremony. Our current laws reflect fundamental reason for marriage, i.e. the formalisation of a partnership which has the aim/possibility of producing off spring. 

No matter which way you want to look at it a gay couple cannot conceive children without unnatural input.  That reason alone in my opinion excludes them from the rite of marriage.  This isn’t discrimination it's a fact of life.

One argument I hear as a reason for gay marriage is to allow for adoption.  While there is no doubt that gay couples can exceptionally be loving parents I believe that every child deserves both a loving mother and a loving father to aid in their development and mentoring.  Boys need a father figure and a mother figure and girls like wise. Two women as a couple or two men as a couple cannot do this. 

I respect a gay couples right to live as a loving couple just as a man and woman do in marriage.  The Civil Union Bill gives them legal formalisation of their partnership in the same manner marriage does.  I don’t see why there is a need to change the laws on marriage to allow gay couples to marry, it won’t enable them to conceive and bear children.  What is being achieved with this bill?
