While I agree with your initial assertion regarding "deterioration of respect for rational thought in primary and secondary education" - I vehemently disagree with your conception of its cause (I recognize some code language here, intentional or not). You call it "emotive subjectivism" - which is a good enough phrase, but I think aimed at the wrong source.
I started a thread before on what I think is the primary cause of that problem (
Is Ignorance of History a Strategy). It's not the "touchy-feelyness" in curricula...(it) is a deliberate effort to "dumb down" education being led by people... to hide their bigoted belief systems. ... It has two components - starve the school system of resources; and inject their idiosyncratic views into curricula. It is behind the rejection of core history and science lessons and the teaching of ancillary experiences (e.g., Native Americans, slaves and former slaves, Chinese immigrants, Hispanics)...in favor of the injections of viewpoint lessons like "creationism" in science classes; and recoding "the Civil War" as "the War between the States" or "The War of Northern Aggression". It includes the elimination of "enrichment" classes - like art and music, advanced education curricula (like international baccalaureate and "AP" classes) and after-school activities. Frankly, conservatives in numerous States have politicized education as a wedge issue and indoctrination opportunity.
