You who raise the young,
With lessons yet un-sung,
Don't teach your children bitter ways,
The thoughts that fuel these broken days.
No tales of hate, no whispers low,
That brand a soul for what they know
Or how they look, or where they kneel,
Or pains that other people feel.
Don't show them walls where bridges stand,
Nor borders drawn across the land
Of shared humanity's wide grace,
Nor darkness in a brother's face.
For some beliefs, once given flight,
Will blot out stars and steal the light.
So guide their minds, but hold the key,
To thoughts that chain and make not free.
Don't teach your children ill, my friend,
Or where such twisted paths must end.
Examples
Here are some specific examples of "bad ideas" (trigger alert):
"My race/religion/nation/gender is inherently superior and others are inferior."
"Child sexual abuse is a private matter or a legitimate practice."
"Torture is an acceptable and effective tool for interrogation or punishment."
"The systematic murder of a specific group of people is necessary for societal purity."
"Denying proven historical atrocities (e.g., the Holocaust) is a valid intellectual position."
"Blind, unquestioning obedience to authority is always the highest virtue, regardless of the act commanded."
"All scientific knowledge is a conspiracy and should be rejected."
"Spreading deadly contagions intentionally is an acceptable form of warfare or protest."
"The Earth's resources are infinite and can be exploited indefinitely without consequence."
"The only valid form of human existence is my own, and all other ways of life should be eradicated."
"It is acceptable to destroy the entire planet to win a conflict or achieve a single objective."
"Subjective personal feelings override all objective reality and shared truth."
"Consciousness is irrelevant, and suffering has no moral weight."
"Rape is a natural expression of desire, not a crime."
"The total annihilation of all sentient life is the logical end-goal of existence."
Note to those who read this far: The emphasis on universal human rights, scientific truth, environmental limits, and equality are cornerstones of liberal thought. Conversely, the specific "bad ideas" on the list (supremacy, totalitarian control, deliberate environmental destruction, rejection of objective truth) often find their most explicit and dangerous expression within extremist right-wing, authoritarian, or nihilistic ideologies.
