As stated, no it is not part of the argument.
I will return to this point about lack of either children or the possibility of children.
That is a reductionist argument. Objectively, it is true only heterosexual couples can have children.
False. Only couples of the opposite sex can have children. The sexuality of either partner does not impact on their ability to have children. If a lesbian is raped by a man she is physically capable of having a child. If a gay man gets married, due to social pressures, then he may have children with his wife. Ted Haggard has children, despite being bisexual, not heterosexual.
They are in the class of people that can procreate together.
Almost everyone is in a “class of people that can procreate together”: males and females can procreate together. There are a few hermaphrodites and others that do not have the required equipment from birth, or have lost it through an accident.
Unfortunately for your argument, almost everyone is also in a "class of people that “
cannot procreate together”. All males are in a class that “cannot procreate together”. All females are in a class that “cannot procreate together”. You are basing your argument here on imprecise and not particularly useful statements.
Why? The truth of the matter is that marriage and children cannot be separated. They are integral to each other.
They can be, and easily are. Many married couples do not have children. Many children are born to single mothers. You are not living in the real world here. Just look at Mary and Joseph. How many children did they have together?
I do not see your point at all? Children are part of the argument. Two men or two women have nothing to do with marriage or procreation.
And many marriages have nothing to do with procreation either. If procreation is essential for marriage, then many heterosexual marriages fail to have that essential. If procreation is not essential, then you need to find a different argument against same sex marriage.
At the top of this post, your said that lack of the possibility of children was “not part of the argument”. Now you are saying that they are. Please make up your mind.
