I’ve had some interesting responses to my post on this topic on Friday. Most who wrote seem to favor a fairly strict licensing policy, while one reader notes the following:

“Fortunately, an easy answer to your concern exists: The Ohio voucher statute upheld by the US Supreme Court in Zelman v. Simmons-Harris required participating private schools agree not to discriminate on the basis of race, religion or ethnic background and not to “advocate or foster unlawful behavior or teach hatred of any person or group on the basis of race, ethnicity, national origin or religion.” (This was cited by Rehnquist, C.J. in his majority opinion.) “

Maybe, but quite how one polices this is a different question altogether.
