Having been one of the students in those classes in the 50's, I can tell you that the problem wasn't that an ideology was being taught, but that only one ideology was being taught. When you say you want this brought back, what you mean is you want your ideology. Not mine, or a Hindu's, or a Muslim, etc. You want Genesis taught, not the Vedas or the Sutras. You call for school prayer, but when the teacher starts handing out prayer mats for the kiddies to bow down to Mecca, that will be an entirely different story.
If you want this ideology taught to your kids, then teach them.
