The Party of Principle

The Libertarian Party prides itself on being "the party of principle". What does this mean? Apparently, one thing this means is that in order to pass muster with the LP, any ideas expressed by an advocate of individual freedom must have (1) been expressed by a founding father prior to 1800, and (2) have been made aware to LP members when they were in the 7th Grade. No post-1800 legal, political, or economic concepts are acceptable, and even pre-1800 concepts are unacceptable if they do not comply with the aforementioned requirements. To the LP member, political evolution, if not technological and cultural evolution, stopped in 1800.
