I found it ludicrous that obviously since she "can't teach her daughter anything" and that her daughter "loves school" and "loves to socialize at school", that obviously any other child just CAN'T learn anything.

Obviously, not everyone's cut out to teach children, and they can send their kids wherever they want. But, they shouldn't assume then that NO ONE can teach their own children, only experts with a planned curriculum can, and anyone else doing so is obviously neglecting and retarding their educaiton.
