Indoctrination of what? Do you think for a second that the teachers in my redneck rural town were advocating for Karl Marx or that my professors in Florida were doing the same? I really hate to disappoint you.
When I say that you can't have a quality education without the inclusion of politics and religion, it has nothing to do with someone pushing you what to believe.It has to do with context. History, politics and religion are completely intertwined and have had constant impacts on one another. Without understanding them all, you can learn the what, but you miss important context that lets you discover the "why".
Dead fascists used to be a good thing. America really is going to hell.
