Actually, if we could get past throwing personality bombs, this thread pretty much addresses the real issues, advantages and disadvantages of charter schools.
If you don't have to take the riff-raff of American society, that public schools are legally required to take, any good school ought to be able to provide a meaningfully better quality education. We used to call those private schools.
The effect, of course, of "public" charter schools is to harm the public schools in several regards, including financially when we use public dollars to fund what used to be private schools.
Thoughtful people of integrity can have different opinions philosophically as to whether that is a good thing or a bad thing.
