More than two genders?
Let’s not get into the whole debate of how many genders there are. Instead, let’s focus on the really matters. This person fails to grasp the concept that a male puppy is the same thing as a boy puppy. We’re giving this person the benefit of the doubt and assuming that they only skimmed through the original post before commenting.
Or maybe this person is actually suggesting the names Boy or Girl for the male puppy. It sounds like a stretch, but hey, this is America. You can call your son Annette and nobody will bat an eye. Well, not nobody, but people are more accepting than they were in the past.
