I don't know why you think this was all "your idea" or that you're some lone wolf. There has been feedback around your exact ideas, as well as Elder's perception of not accepting of outsiders for years.
This feedback has been happening for years, and not on here, but in real life. You're not a trend setter, but you are not in the minority either. That's why I don't understand why you attack everyone that basically has the same opinion as you. It's like you want credit for the revolution.
How much noise do you think they received after the basketball incident? It was alot. It was exact same ideas that they have to start opening themselves up to new ideas, cultures, and types of people, and start teaching their students this as well. They have to get away from this insulated view of like people, minds, and ideas. This doesn't directly play into your idea about non-feeder kids, but it most certainly applies.
What has happened since that uproar? It's been almost a year. It tells you all you need to know. But keep acting like all this ain't real. There's zero chance they will be successful accepting outsiders by just saying "we accept outsiders". That's why your demand they just go out and find non-feeder kids is so unbelievably unrealistic.
It could be a huge success. I'm with you there. But it's not something you can just flip the switch on. It's not marketing and billboards and an Admin Director knocking on doors. It's a choice to do things differently so others feel they are welcome and that the school provides opportunity to everyone.
I post all this, and then people say "all you do is badmouth them" - this isn't badmouthing anyone.
