Your daughter must just intimidate the hell out of them! All those grown-ups afraid of one little girl....pathetic.
I think you should homeschool and I think you should start now! Why wait for the end of the year? Do you really want people this unreasonable to have access to your child all day? Nothing pisses me off faster than when someone implies that i'm pushing my son. They should all be forced to live with him for a week: I guarantee that they would rethink their comments!
I'd also do whatever I had to in order to get my deposit back. Get the State BOE involved, file a suit, whatever....
And you're right, it is nice to know you're not in this alone, it's what keeps me coming back!
Good Luck!
