I think a lot of us want pet parrots because we don't quite grasp what it means for them to be our pets and how stressful (even with loving guardians and good care) that that can be. Soon enough we get wise to it.
Personally, It's not ok with me to throw my hands up and say 'well because I can't do everything, I'm going to do nothing'. I would never go vegan for example.
I know then that one could ask me why bother getting upset at keeping parrots as pets. I would argue because there's a huge difference between killing another life for sustenance and then keeping a life for your entertainment. Especially a life that is clearly not adapted to living as a 'pet'. Most of our now domesticated animals actually do fairly well living with us so it doesn't bother me as much.
I lived in a community where the dogs were allowed to free-roam and form packs and socialize with other dogs. They were affectionately known as 'town dogs' and were collectively cared for by the community--if it was cold someone brought them into the garage for the night to keep warm. The dogs came and went to their families as they pleased.
The most well-adjusted cats I've ever seen belong to a friend who has a small farm. They sleep in the loft in the barn, spend their days catching and killing rodents and other prey---and can climb trees at will. They're still very affectionate cats.
Sure---one day they could get killed by a coyote, or a dog, or the dogs could get hit by a car or something. But to me that's a worthy tradeoff. They're alive, living fully enriched lives.
If someone was raising their children like we do our modern pets people would say they were sheltered and smothered. You can't bubblewrap someone and never let them live. Like...to be 100% safe 100% of the time... it messes with the quality of life, because very few things are 100% without risk.
I feel the same way about Jacko. I'm not about to let my selfish and greedy attachment to her and not wanting to feel loss and pain prevent her from living if I can help it.
Don't want to start a fight

just my two cents.
