How is anybody supposed to know on sight a bully that has come from a loving home and is gentle or a bully that is kept in a cage 16 hours a day and is reactive?
My child is at bully face height, I move them away from large dogs when I can but especially large bully breeds because they are the most likely breed to maul a kid to disability or death. (I also steer away from guard dog type breeds like malamutes, German shepherd's, doberman and rottweilers even though my brother had a lovely female rottweiler many years ago)
You can't be offended if people stay away from your dog, (edit: especially if their dog is reactive and barking they are trying to avoid a fight!) it reminds me of my male friend complaining that a woman crossed the street when she was walking home alone at night. People shouldn't be guilted into putting themselves in uncomfortable positions, even if the risk is low, to save someone else's feelings.
