My point is that people who opposed interracial marriage thought that they had a rational basis for doing so (even though it didn't make sense); similarly, people who oppose gay marriage today also think they have rational bases for doing so, even though they don't make sense.
> they can be rational and maintain that a relationship between two people categorically incapable of producing children together biologically, two people of the same sex, can’t be a marriage
Pretty much nobody actually makes this argument, though. Probably because infertile people get married all the time.

Not really, as I said before there’s no biological basis for refusing to accept an interracial relationship as a marriage.
I'm not going to continue defending views that aren't my own, so if you're interested in reading what exactly "traditional marriage" defenders are talking about then try this review: http://www.harvard-jlpp.com/wp-content/uploads/2013/10/Georg... (pdf)
