I can't be bothered to read the 21 pages of this thread: way too much drama.
I can't help observing there are maybe a dozen or so Chinese immersion programs in the US. That leads me to think that you should go ahead and start a school, it's obviously easy to do. That's why so many other districts have succeeded, right?
No seriously, do it.
Until you came along, probably nobody even thought to sit around bitching on the internet instead of actually creating something. You should keep doing that - it's the epitome of innovation! Thanks for being part of the DC public/public charter community of schools - you're a jewel.
