I just ignore it. I don't have time to argue. If someone asks a question and gets the right answer and refuses to run with it, that's on them. Their animals might pay the price for their stubborn ways but it's not something that can be helped by anyone but them. You mostly see this when it comes to husbandry and the equipment needed for it. Thermostats comes to mind. They get an answer and it involves buying something so they ignore that part and keep asking questions to make what they have work. The answers don't change. You can choose to listen or not. Some people come across as snotty when they don't mean to be because they don't use emojis or lol after every word. The advice is still the same. My favorite is when someone ignores or challenges advice because a "breeder" told them different.
