Why do Republicans act like the Founders were some monolithic bloc who all believed the same thing, when they were in fact as ideologically diverse as Congress today? What did Patrick Henry and Alexander Hamilton have in common, other than not wanting to be ruled by King George? No, "the Founders intended" is just code "I'm going to make up a justification for my already-existing opinions."
No, Hamilton and Henry were polar opposites. Quit making up strawmen. Nobody is claiming they are monolithic. "The founders intended" is a complex argument. Keep in mind, the Constitution is the coming together of Hamilton and Henry, Jefferson and Adams, and so on. It was a compromise.
Secondly, the nation that the Founding Fathers wasn't great. Sorry, Founding Fathers, but you didn't built that. Future patriots like William Lloyd Garrison, Abraham Lincoln, Susan B. Anthony, William Jennings Bryan, Theodore Roosevelt, Franklin Roosevelt, Martin Luther King, Lyndon Johnson, and Barack Obama made that happen.
This second paragraph is just your subjective opinion and is highly irrelevant. My side has Ronald Reagan, Barry Goldwater, Grover Cleveland, and Bob Taft, Ron Paul, Calvin Coolidge, Isabel Paterson, Zora Neale Hurston, and so on.
