The most tragic thing about this is that she isn’t even using the word breedable correctly. The traditional meaning of the word, which she is trying to gatekeep, means to produce offspring. Humans breed by procreating with another human to create human children. Vaginas do not breed with other vaginas to create vagina children, so vaginas are not breedable.

Even if you think the slang form of the word breedable this guy used is invalid, he’s still breedable as long as he’s capable of impregnating someone, even if he has no desire to do so.
