Asked to produce evidence for the "negative impact" of gay marriage on traditional marriage, or society in general, all he could muster was "I can’t necessarily get into statistics". Indeed he could not, because, as I already noted, the 2010 Census indicates that 3 in 5 families have no children under 18 living with them. Therefore his belief that same sex marriages could be harmful to children is both unfounded and largely irrelevant.
Of course this did not stop Tyree from claiming that "the original intent of a marriage is to procreate". I'm not sure if all religious fanatics feel entitled to just make s*** up whenever it suits them, but apparently Tyree does. Let's take a look at what the Bible actually says, shall we?
According to Genesis 2:18 God says, "It is not good for the man to be alone. I will make a helper suitable for him." In other words, God wants a companion for Adam. That is his *ahem* ORIGINAL intent. God then tries to make various animal pets for Adam, but Adam doesn't want a puppy or pony, as God discovers (Gen 2:21). So God induces a coma in Adam, steals a rib and makes Eve, as the bizarre story goes.
So what was Adam's reaction? Did he say, "Oh boy, it's time to procreate?" No, sorry, he does not. Instead Adam finally likes this companion and says, "This is now bone of my bones and flesh of my flesh; she shall be called ‘woman,’ for she was taken out of man", as though Adam new where she came from (Gen 2:23). The point, however, is that Adam does not identify his desire to procreate with her as having anything to with being pleased with Eve. He simply likes the fact that there is a second creature in the world who is like him. Of course, fundies love to point out "Gawd made Adam and Eve, not Adam and Steve", but from these verses it is clear that Adam would not have cared. He just wanted a friend who was made out of the same bone and flesh that he was. Either Eve or Steve would have fit that bill.
Now, often times religious whackadoodles attempt to fire back with the "be fruitful and multiply" line in Genesis 1:28. For the record I will note two issues with this. Firstly, says absolutely nothing about marriage. It is addressed to both men and women, but clearly men could not be "fruitful" in the sense of becoming pregnant, like women. Secondly, I will note that this same verse says, "have dominion over the fish of the sea, and over the fowl of the air". Does this mean that God wants us to own a pet fish and bird too? Maybe that's part of God's plan, Mr. Tyree. Why don't you get working on that. I'm sure that petshop owners will love you for it and then you can find something to occupy your time instead of bashing gay people.
