There is one human race and humankind is two-sexed.
Oh, and the nature of marriage is two-sexed and procreative in kind.
On the other hand, a relationship, sexual or not, that excludes the other sex is sex-segregative. Maybe that can be a good thing or a bad thing or a neutral thing. But it is a fact that male-only or female-only twosomes (or moresomes) lack the nature of marriage which integrates man and woman and provides for responsible procreation.
There's one human race. Humankind is not a series of subspecies. The nature, or essence, of the marital type of relationship demonstrates this for all of society. Marriage is not segregative by sex nor by "race".
There are other kinds of relationships, of course. And the essence of this or that type may be meritorious, sure. Just as this or that type of association amongst people be that based on any human characteristic may be meritorious. Or not. But there are different types of human relationships as their are different types of human associations.
That's life.
