I'm a dog person, but I agree, for the most part. Nobody should have to put up with wild, untrained animals in public places. That's kind of the point of civilization- taming and controlling nature. Untamed dogs do not belong.
That said, I think properly trained dogs are less offensive than most people. I do my best to train my dog, and I actually think she still has a long way to go. (She is very obedient, but being young, has a very short attention span and requires repeat commands to stay focused.)
The average training level of dogs these days is simply atrocious. I went out for a walk on a trail that allowed off leash dogs, and several people told me how shocked they were that my dog always came and stayed by my side when I commanded her to "heel" -frankly, this is disturbing. I consider a reliable recall the BARE MINIMUM for a dog.
"Good" dogs are usually the most predictable, reliable things in their environment
