I think it's important to recognize that we all started someplace.
Look at how many of us that have rescued parrots that never left a teeny cage that wasn't even cleaned - i suspect that's way more common than we realize. Yes it's terrible because we know how advanced these species really are, but there are soooo many people out there that just don't know this yet.
I give credit to the OP for coming here and reading and asking questions. It's not easy to keep trying and learning when the idea you had about how parrots are as pets is so different from everyone answering, but they're still here.
When I was visiting Cotton every few days at the rescue, I saw at least 15 people every day come in and ask "which one talks, and how much do they cost?"
There is a huge gap between people who have learned what being a good parrot owner means and people who have only ever heard of parrots being a cool thing to show off.
IMO there's a lot of room in the middle to keep trying to meet someone where they're at.
ETA that said, I do appreciate that we have a range from gentle to blunt on this forum, because I for one needed to hear things both ways to get it!!
