Are they easy to train? Largely.
Are they easy to live with? Nope. They have endless energy, less than awesome off-switches, prone to obsessive behaviors, can be less than socially normal (not your stereotypical golden), can be smarter than you, and can be extremely forceful.
Are they alone in this? Nope. Most people have no ability, desire, or reason to own a true blue pit bull either. My client with a Kishu Inu and a Hokkaido Inu bewilders me. They are hard to work with, they have tons of quirks, they howl all of the time, they can be extremely snarky and even more extremely hard to motivate. I also have a client who desperately wants to do agility but she has a shiba inu and well, she's just... upitcreek.
Would I have it any other way? Nope.
Are we being elitist? Some yes, some no. Some of us are making an effort to protect our breeds, some are proud, some are serious.
I don't believe in the slightest it's a matter of wrong dog. I know for a fact my dogs are hard to own but they are perfect for us.
