I agree. It’s an individual thing. Each home is different, each bird is different.
With that said, I do clip(except Emma who is special abled and cant fly)
because I can not guarantee that my doors will always be shut, and another concern of mine is a larger, heavier species flying full force into the window screens in the summer. My house if full of huge windows. I cant guarantee that each and every screen is securely in place each and every day in the event one is hit by a flying parrot.
So what works for one may not work for everyone,tho some refuse to see the other side of the coin.
One must do WHAT'S BEST for their bird in THEIR home.
Kudos to the people who are able to secure a safe home for your birds, that will allow free flight. If that is what you choose to do, I suggest following the training from a reliable source, and not just anyone off the net. There are some highly marketed training materials out there that are at best weak and at worst dangerous, and one to many with little or no experience overall, acting like trainers... My suggestions being:
Parrot Training: Behavior, Flight and Enrichment or something like Barbara Heidenreich's
Good Bird Inc Parrot Training Talk .
Kudos to those of you who relize you are unable to keep a safe house and take precautions that you are able to, which might include clipping.
No one can tell you what is right or wrong in your home....BUT YOU.
