Confusion strikes again: What is a couple?

Set aside the distraction that we are discussing something that both of us care deeply about, so our personal stakes are high. Just enjoy with me this intellectual banquet.

Another intriguing feature of the Oxford Dictionary definition is that it does not contain any basis for the idea that the number 2 is significant or special. "Married or closely associated romantically or sexually" could equally as well be applied to a sex commune of twenty people who live together. In contrast, the reproduction paradigm that I use to define "couple" contains a wealth of biological and institutional detail from which we can construct rationales for why a male-female pair is distinct and important. You correctly see that the same biological and institutional detail provides a solid foundation for rationales for why male-male, female-female, male-horse, female-donkey, 10-male-10-female, male-female-cadaver, female-male-child, male-female-child (and the list goes on) combinations are morally wrong (perverted). In each of these queer sexuality modes, the biological and institutional detail supports arguments that queer sexuality of the mode being considered harms the individuals involved and/or the community in which they live.
