I've seen nothing since then to persuade me (government) gained in wisdom, common sense or humanity... as recited dramatically although historically thus accurately by Colonel William Ludlow, as portrayed by actor Anthony Hopkins...

"Indians! Indians were the issue in those days. There is nothing as grotesque as the meeting of a child with a bullet or an entire village slaughtered while sleeping. That was the GOVERNMENT's resolution of that particular issue. I've seen nothing since then to persuade me it's gained in wisdom, common sense or humanity."

Colonel William Ludlow, as portrayed by actor Anthony Hopkins in the 1994 film Legends of the Fall, direction by Edward Zwick, screenplay by Susan Shilliday and William Wittliff.

Like the lines recited in the film dramatically although historically thus accurately representational, I too find little evidence the US Government have "gained in wisdom, common sense or humanity" since the 19th century if not lost what little of such character during the 20th/21st centuries, that is to assume the actual, initial existence thereof.

First and foremost, political rhetoric presumes the use of force then government policy violates by use of force. The presumption and violation always proceeds then tramples upon previously, rightfully voiced dissent, per the former's impatience or unwillingness for mutually respectful discussion towards ethically consensual unanimity. 

Astonishingly, most everyone still contend today, the most educated, enlightened of American eras, their preferred politician or party will make the moral difference.

Come let us Reason. Peace is always a Choice.
Study, Ponder, Labor, till last Breath.
