I typed out a long post, only to lose it as I've just had a short power cut!
Okay, dogs should be trained not to pester people, but IMO people who don't like dogs are just plain wrong, and overreact a lot too.
Try seeing things from the other point of view, why don't you.
I don't like dogs because I was attacked as a child. I have, over the years managed to get to a point of being able to be near dogs, but struggle still to touch them, and certainly never trust them. The dog that attacked me gave no warning signals whatever, even the owner was taken by surprise and I was nowhere near the dog in the first place. I only got bruising as I was wearing thick clothes, but it was still a frightening experience.
My brother was attacked by a dog as a child too. In his case, he got several deep bites from a jack russell. The owner didn't even bother to stop and help my brother, just said "you'll be fine" and walked off. Dbro was simply playing in the park, and was not near the dog, so no excuse of provoking the dog here.
Dbro only got help cos his friend who wasn't attacked came and got my mum. This was about 30-35 years ago.
