Dovers old school board never included intelligent design in the science curriculum.
I'm not an ID advocate. Evolution, small e, is an observable fact and intelligent design, small id is an observable fact.
I'm a committed creationist, Catholic style.
I don't think public schools should be proselytizing one religion at the expense of others. But I include secular humanism in their as well.
A disclaimer does not establish nor favor any religion. Ergo, the federal government has no dog in the fight. The remedy for school boards not representing the views of the locals is for them to be removed electorally which is exactly what happened in Dover before the robe began his proselytizing.
A constitutional republic works, if we let it.
"The robe" began because people brought the case to it.
Dover's school board mandated the teaching of intelligent design, and intelligent design is religion wearing a disguise, so, in effect, Dover's school board mandated religious teachings to be included in a biology class.
Had the Dover city council mandated that teaching evolution be included in Sunday class, people would have argued that the Constitution forbids such a thing.
Yet, they are the same thing.
