Revisionist History Myth #1: FDR was a great president who ended the great depression with the New Deal. Fact: FDR was a power hungry tyrant who exploded the size and scope of government and prolonged the depression with the new deal.
The revision is your version...the truth may be somewhere in the middle. The fact is we can't test the theory that the New Deal prolonged it. FDR is a mixed bag - he definitely tried to strong arm his policies through in what at the time was viewed as an emergency situation - it was the Great Depression after all.
Revisionist History Myth #2: The civil war was about slavery. Fact: The civil war was about state's rights and the south seceded because they were worried about the ever growing reach of the federal government.
Again, your angle is the revision. The reason there was a north and south was slavery. The reason the South feared the Fed was because of the threat to slavery - nothing more nothing less. I find it pathetic that 21st century southerners are wasting time trying to justify a blot on our history.
Revisionist History Myth #3: JFK was a liberal hero who championed liberal values. Fact: JFK was a fiscal conservative who would not find room in the democrat party today. He advocated for deep tax cuts, something that democrats to this day do not want to hear about and downplay. Revisionist History Myth #4: Ronald Reagan was all for open borders and amnesty. Fact: Reagan passed amnesty in exchange for tight border security and a closed border. But democrats with their typical Lucy & The Football ways never followed through on the border security part.
Each party has their myths....the Republicans have many around Ronald Reagan...a man who may have a tough time finding a home in the modern Republican party.
Revisionist History Myth #5: Democrats passed the civil rights act. Fact: Republicans passed the civil rights act.
Northern progressives/liberals passed the Civil Rights Act....I don't think party affiliation is that important.
