This is the flag under which the Continental troops stood against the British Army in the Battle at Bunker Hill on June 17, 1775.  Because pine was a superior material for masts of the British Navy, Parliament banned Colonials from cutting down any white pine trees - even on their own property!  Thus, the white pine tree was a symbol of British tyranny.

The white pine tree has become our symbol of resistance against state subverting society for its own ideological purposes, and interference in parents' rights to raise their own children by their own values.
