Tell me, did the Founding Fathers ever claim to be libertarians or to represent libertarian philosophy?
If they did, you have a point.
If they didn't, it's utter bollocks yet again.
Encyclopedia Brittanica:
"Although many of the Founding Fathers acknowledged that slavery violated the core American Revolutionary ideal of liberty, their simultaneous commitment to private property rights, principles of limited government, and intersectional harmony prevented them from making a bold move against slavery. The considerable investment of Southern Founders in slave-based staple agriculture, combined with their deep-seated racial prejudice, posed additional obstacles to emancipation."

Online Etymology Dictionary:
"liberal (adj.)
c.1375, from O.Fr. liberal "befitting free men, noble, generous," from L. liberalis "noble, generous," lit. "pertaining to a free man," from liber "free," from PIE base *leudheros (cf. Gk. eleutheros "free"), probably originally "belonging to the people" (though the precise semantic development is obscure), from *leudho- "people" (cf. O.C.S. ljudu, Lith. liaudis, O.E. leod, Ger. Leute "nation, people"). Earliest reference in Eng. is to the liberal arts (L. artes liberales; see art (n.)), the seven attainments directed to intellectual enlargement, not immediate practical purpose, and thus deemed worthy of a free man (the word in this sense was opposed to servile or mechanical). Sense of "free in bestowing" is from 1387. With a meaning "free from restraint in speech or action" (1490) liberal was used 16c.-17c. as a term of reproach. It revived in a positive sense in the Enlightenment, with a meaning "free from prejudice, tolerant," which emerged 1776-88. Purely in ref. to political opinion, "tending in favor of freedom and democracy" it dates from c.1801, from Fr. libéral, originally applied in Eng. by its opponents (often in Fr. form and with suggestions of foreign lawlessness) to the party favorable to individual political freedoms. But also (especially in U.S. politics) tending to mean "favorable to government action to effect social change," which seems at times to draw more from the religious sense of "free from prejudice in favor of traditional opinions and established institutions" (and thus open to new ideas and plans of reform), which dates from 1823."

Liberalism, Wikipedia:
"The American War of Independence established the first nation to craft a constitution based on the concept of liberal government, especially the idea that governments rule by the consent of the governed. The more moderate bourgeois elements of the French Revolution tried to establish a government based on liberal principles. Economists such as
Adam Smith, in The Wealth of Nations (1776), enunciated the liberal principles of free trade. The editors of the Spanish Constitution of 1812, drafted in Cádiz, may have been the first to use the word liberal in a political sense as a noun. They named themselves the Liberales, to express their opposition to the absolutist power of the Spanish monarchy."
More importantly, I invite you to look up Classical Liberalism or traditional liberalism, which is what the majority of the founding fathers were.
http://en.wikipedia.org/wiki/Classical_liberalism
"Classical liberalism (also known as traditional liberalism[1] and laissez-faire liberalism,[2] or, in much of the world, simply called liberalism) is a doctrine stressing individual freedom and limited government. This includes the importance of human rationality, individual property rights, natural rights, the protection of civil liberties, constitutional limitations of government, free markets, and individual freedom from restraint as exemplified in the writings of Adam Smith, John Stuart Mill,[3] Montesquieu, Voltaire,[4] Thomas Paine and others."
