The real Boston Tea Party was a protest against huge corporate tax cuts for the British East India Company, the largest trans-national corporation then in existence. This corporate tax cut threatened to decimate small Colonial businesses by helping the BEIC pull a Wal-Mart against small entrepreneurial tea shops, and individuals began a revolt that kicked-off a series of events that ended in the creation of The United States of America.

They covered their faces, massed in the streets, and destroyed the property of a giant global corporation. Declaring an end to global trade run by the East India Company that was destroying local economies, this small, masked minority started a revolution with an act of rebellion later called the Boston Tea Party.

The teabaggers know jack about history and would have been thugs in the employ of BEIC back then, helping them to maintain monopolies and benefit from colonial taxes rather than paying a corporate tax to the crown.
