Is hating families a form of bigotry?

(Note : Not referring to Grove Street Families, but instead the concept of families)

If disliking someone due to their race, nationality, sexuality… etc are all bigotry, since they are aspects of being one is born with & cannot control, would the same apply to instances of hating an entire family? Not just families that are famous & hated, but even small unheard of households that you have a personal grudge against
