The defining war for:
Libertarians - The Revolutionary War (we won)
Conservatives - The Civil War (they lost)
Liberals - The Vietnam 'war' (we lost)
So when talking to someone from one of these three groups, recall which frame of mind they're approaching the conversation from. Alternatively, these facts can act as discriminators, to determine the political ideology they possess.
Can you think of any others? Maybe most favorite/least favorite ammendment, (least) favorite president, etc.
In fact—
Favorite President for:
Conservatives - Ronald Reagan
Libertarians - Thomas Jefferson
Liberals - Barack Obama (and he's only been on the job 24 hrs!), or maybe Lincoln or FDR
Least favorite President for:
Liberals - hard to call... three-way tie between Reagan, Nixon, and Bush (depending on what generation)
Conservatives - Barack Obama (and he's only been on the job 24 hrs!)
Libertarians - Dunno... John Adams, father of the Sedition Act and enemy of TJ?
As always, I welcome any debate.
