What next, we can defend "tall" being anywhere from 1mm to 9 feet because height is a continuum?
Words have meaning so they can be used for communication. If I use the word inbred to mean two siblings having a child and two partners sharing an ancestor 20 generations back, I'm not communicating anything when I use the word inbred.
And pointing out that closeness of ancestry is a continuum is not a defense of using that word in that manner.
