You are so right - and this is an award-winning school district.
You should hear the stories of those who send their kids to the Philadelphia or Chester-Upland public schools. No education would be better than most of those schools.
"Philadelphia"
The difficulty with the argument is, just because one's personal experience with a school or school district isn't acceptable doesn't mean that ALL public schools are bad.
It's like some terrorist professing to be "Christian" means all Christians are bad.
