Here we go with the common core backlash...
Lets say a great many people all need to do something in their lives that the vast majority believe could be improved, backed by numerous scientific studies. A program is devised based on many years of research that attempts to change the focus of this task from memorization to understanding. Since this is a significant paradigm (sorry) shift, those who came up from the old system are confused and as with most new programs there are a few bugs to work out. Should we:
A) Tweak the program and let it evolve with the population since everything we know says we should try it
B) Start a vast national smear campaign with the goal of shutting it down and ostensibly going back to the old system because no one is proposing an alternative*, just because the "other guy" was in office when the plan was implemented.
*I would count your "wonders of math" as an alternative if some details were provided instead of being presented "TrumpStyle"
