There was no “evidence” in the article to support your assertion that charter schools are “preventing at-risk youth from getting an education.”
It’s funny, because I actually know that there are some charter schools which are mishandling their at-risk youth. Just as I know that there are some public schools doing the same thing. But that’s not what public schools generally do, and it’s not what charter schools generally do.
My entire point is that dismissing charter schools out of a reflexive distrust of private enterprise is as useful and fact-based as dismissing public schools because of a reflexive distrust of government. And both attitudes explicitly ignore the families who are well-served by both.
