He definitely shouldn't expect people to leave their dogs at home just because his daughter doesn't like them, but people shouldn't have their dogs off-leash, allowing the dog to run up to any and everyone. It's unkind to people that might be frightened, and unfair to other dogs on-leash that might not respond well.
My current dog, a rescued Great Dane that is a big girl with an unknown past, loves people but has an aggressive fear response to other dogs. If your off-leash dog runs up to us, we all have a problem. I've taken 3 small, off-leash dogs out of her mouth and thankfully injuries have been minor. I dread the day a big dog comes at her because if that happens I'm going to have to drop the leash to keep from getting tangled up and injured myself. Who knows how it'll play out but I'll likely be suing some idiot for vet bills that could have been avoided by keeping their dog under control.
