Supreme Court Same Sex Marriage Argumet

[paulpablo]

Indeed you can and it follows by answering these questions regarding procreation:

1. how many people do you need (at minimum) to procreate? 2
2. what genders do those people need to be? Opposite
3. what minimum age do they need to be? Of pubescent age (about 13)
4. what familia relationship? Different (or at minimum not immediate)

Thus, the procreation centric definition would be 2 people, of the opposite gender, that are at least of pubescent age, who are from different families (or at minimum not part of the same immediate family).

But what is that a list of?  Some of them are biological truths, such as the genders need to be opposite, they need to be of an age where they can have children.

But members of the same family can produce offspring but with there being more chance that the offspring will suffer from abnormalities or death.

So with that in mind this list is incomplete.  If you were to go by what you call the procreation centric view of marriage then no one over the age of late 40s should be allowed to be married because at this age the offspring is at a great risk of having down syndrome. 
Also straight people who just can't have children because of sperm or ovary abnormalities should also not be allowed to get married.
