Substantively, Thomas has completely missed the boat on this issue. First, the government has no business, secular or otherwise, being involved in the education of anyone. And second, the Federal Bench has neither the jurisdiction nor the right to rule on anything decided by a local school district. The judge found some imaginary separation of church and state in the US Constitution which, even if it existed, would not apply to this case. Thomas is welcome to his cultural opinion, but he is all wet on his opinion of the jurisprudence (or actually lack thereof) in this case.
If Thomas was a real conservative, he would have left the cultural issue out of the article and addressed the blatant disregard of the US Constitution exhibited by the judge. When or if this case reaches the SCOTUS, hopefully that bench will be populated by originalists who will quite correctly rule that the US Courts have no jurisdiction in this case and toss the whole thing out on its ear.
