“Our enemy is power mistaken for justice. Our enemy is the desperation that justifies atrocity. The Jedi's true enemy is the jungle.”

Context: For Negroes are not the only victims. How many white children have gone uneducated, how many white families have lived in stark poverty, how many white lives have been scarred by fear, because we have wasted our energy and our substance to maintain the barriers of hatred and terror? So I say to all of you here, and to all in the Nation tonight, that those who appeal to you to hold on to the past do so at the cost of denying you your future. This great, rich, restless country can offer opportunity and education and hope to all: black and white, North and South, sharecropper and city dweller. These are the enemies: poverty, ignorance, disease. They are the enemies and not our fellow man, not our neighbor. And these enemies too, poverty, disease and ignorance, we shall over, come.

Fánshì dírén fǎnduì de, wǒmen jiù yào yǒnghù; fánshì dírén yǒnghù de, wǒmen jiù yào fǎnduì.
If the enemy opposes, we must support it; if the enemy supports it, we must oppose it.
