The dominating Leftwing faction of media is a greater threat in my opinion.
A dominating Leftwing media would be impossible in a nation of morally grounded, God-fearing, and educated citizens ( as Jefferson warned) .
A morally well-grounded, God-fearing, and education citizenry can not be produced in a socialist-funded, single-payer, and compulsory system of indoctrination centers. All it took was one to three generations of this indoctrination to give us Woodrow Wilson and Franklin D. Roosevelt.
Example:
Beginning of state ordered socialist-entitlement schooling: 1853
My great-grandparents born 1860s
My grandparents born 1890s
My parents born 1913
All of the generations above thought Franklin D. Roosevelt walked on water and that socialism was their redeemer and savior. That is was socialist school does to a free people in less than 3 generations.
