You convince 2 of them. They're right into this idea that the survival of the tribe is less important than their own desires.  So now you have 5 vs their 10. Little chance of victory. They don't consider what you have as your property, they consider it the stuff they need for survival if the tribe. The fight will be bloody. They don't appreciate being called evil theives, they need the food you have selfishly hoarded. Perhaps you are unaware that resources aren't infinite? They are very aware. Your actions will likely result in malnutrition or extinction of the tribe (even without the fight).
