I’m not agreeing or disagreeing with you yet, but I think it would be helpful to provide some more concrete examples of “scientific gibberish” and philosophical indoctrination happening in schools. News articles, papers (but from credible sources), etc.
(FWIW, I’m not counting blog posts written by militant atheists bemoaning Creationism taught in schools. They may be atheists, but they do have a point in protesting something that has clearly Christian (and non-Catholic Christian at that) undertones in public schools.)
Again, still not disagreeing with you, but I have to also express how skeptical I am that there is a widespread problem of schools and universities subtly indoctrinating students with philosophical and political ideas through science classes. Why? I know this is just anecdotal, but I have never experienced anything like this, or have known anyone to experience this. Having attended both parochial and public schools, none of my science instructors had subtle philosophical agendas. At least in my state, there are statewide standards imposed on both public and parochial schools as to what should be taught in science and social studies classes, tested at the end of the year. AP classes, which have the same curricula and textbooks across public and parochial schools nationwide, have even more rigid standards. How can you have time to veer off the lesson plan when you are worrying about your students knowing the concepts well enough to pass standardized tests?
There’s more room for individual professors to inject their own agendas at the university level, but this simply hasn’t happened to me at the classes I took at both state and catholic universities. If anyone has had a different experience, I’d be interested to hear it. Even then, 100 level classes are also standardized to the extent that one of their main purposes is to prepare students for exams like the MCAT and GRE.
So, if we can assume that science education has some level of standardization, the implication would have to be that if there is some malicious agenda underlying science education, it would have to be a widespread problem.
TL;DR: I’m arguing public and parochial schools, at least in my area, pretty much teach the same things.
