I have been culling animals before there were computors, but not before their were dictionaries, which I try to not change the meaning of words. Breeders have been cullng stock for centuries, not all go to slaughter. A good breeder sells some culls, that doesn't mean they are decrepit, it might not be the best, only a fool would sell the best, but it doesn't mean their not worthy to breed.by saying cull to mean kill you change English language, not all oldtimers I know do that. Pretty soon nobody knows what you mean. Cull, remove, kill,process, slaughter..say what you mean, there is no fufu here.
