It is not only subjective, some of it is downright wrong.
For instance, they jumped right from the first settlers to the "heroic Bostonians that gave the gift of freedom to all of us."
WTF????
They skipped the French and Indian War. They failed to mention that the only taxes levied against the colonists were to pay for the huge debt of protecting them during the French and Indian War. Even still, those taxes were in reality about a third of the tax bill the average Londoner paid. In today's situation, it was one fifth of what our tax bill is.
Then they talk about the Boston Massacre. They portray the people shot as completely innocent martyrs. Huh? The troops were there to put down insurrection that was bloody and violent. The malcontents, including Atticus, were armed with clubs, cobblestones, and farm tools and had drawn first blood by attacking the trroops that were attempting to make them disband and go home--peacefully. The crowd turned on them, and a nervous soldier pulled the trigger.
Then they go on to talk about the innovation of warfare in that true American spirit ingenuity they employed snipers, hid behind rocks and trees, and attacked helpless noncombatants in a deliberate campaign to induce fear in those loyal to the crown. In fact if you read the newspapers and correspondence of that time, you will see description of American behavior described the same way we talk about terrorists.
Talk about revisionist history. . .
