Its not dog hating to expect other people to control their dogs and follow the law. But people are not obliged to love or even like dogs either. I can see both sides here to be honest.
I was attcked by a Rottweiler when I was 18, was part of college training to be nursery nurse and I was supposed to be nannying for this family. They had Rottweiler who they wanted me to "get to know" before starting my actual placement so I went to visit one day, Dog came in room snarling and acting pretty aggressive, told the Mum I wasn't comfortable and to please keep dog back, at which point she told me he's just wanting to play and unleashed it, fucking thing jumped and latched straight onto my face. This was a dog described as a big softie, a family member, a docile giant etc. It really affected me and impacted on my life. Little things like going to the shop started taking half an hour instead of five mins as I'd plan routes that didn't involve walking past dog walkers, most s don't let dogs go jumping and harassing strangers, but enough did and then get angry with me for asking them to retrieve their dog, I'd explain what happened and why I'm nervous but they'd tell me I "have to learn".
I'm much better now, it took a long time but I'm comfortable around most dogs, still don't like random owners letting their dogs jump at me and tell me they are just playing and are soft, I used to get awful flashbacks when I'd hear that, it was always said in a dismissive way. It's daft to suggest that all dogs shouldn't be off leash at all, but can totally see why some feel that way as there's an alarming amount of owners who think letting their dogs jump up at strangers is cute and ok and people who don't like it are miserable dog haters. I also feel that some dog owners take someone not wanting their pet all over them as a personal insult to themselves, which is daft.
I know that not all dogs can bite, I know that not all dogs of a certain breed will be aggressive, I have a few friends with dangerous type breeds, but I'd be a liar if I said I wasn't more mindful of certain breeds. A good friend had a staffy, she's a love,y woman and a great friend but not a great dog owner, I ended up refusing to be around the dog as she had zero control of it and it would snarl and growl, it hated being off leash so she didn't use one, had no recall at all. and she would then get upset when people push her dog down, call it a name or tell her it needs muzzling when it's trying to chew their legs, she fed it chocolate and junk because she'd feel bad at leaving it out when her and dc were eating chocolate, she ended up killing the dog doing that. She knew chocolate was bad for dogs, but said it looked "jealous" of them eating it..
I know a lad with a pit pull cross, he looks like the "stereotypical" type who buy these dogs, but he's actually got one of the most well behaved dogs I've ever know, would I want it off leash around me? Probably not, but isnt an issue, if I were in his house dog would be in playpen, he never takes it anywhere without a leash and muzzle, he'd never forgive himself if something happened and dog was punished for him being irresponsible.
I know you said you can see for miles but you just can't see everything, it's not just people and other dogs you need to see, it's other animals like rabbits etc, also, dogs senses are better than ours and your dog could be after something long before it's come into your view. A training line and muzzle are good ideas and I'm please you're going with that. I know you love your dog, but it's best not to do anything that could have someone reporting you and putting dog at risk.
