Reading about the lunatics' response to a proposed presidential taped message to school children, I have seen several references to Pink Floyd's great album "The Wall".
While the ones I've seen have not pulled out a specific line, I presume, from the tenor of their other comments, these people refer to the lines "We don't need no thought control" and "Hey! Teachers! Leave them kids alone."
In other words,we don't want the President of the United States to address our children because we think he'll take the opportunity to indoctrinate them into "socialism".
These people are in fact building a wall for their children brick by brick: a brick of intolerance, a brick of suspicion, a brick of racism, a brick of hate....
Perhaps these people should read further in the liner notes of the album for these lyrics:
The Thin Ice (Waters) 2:28
Momma loves her baby
And daddy loves you too.
And the sea may look warm to you babe
And the sky may look blue
But ooooh Baby
Ooooh baby blue
If you should go skating
On the thin ice of modern life
Dragging behind you the silent reproach
Of a million tear-stained eyes
Don't be surprised when a crack in the ice
Appears under your feet.
You slip out of your depth and out of your mind
With your fear flowing out behind you
As you claw the thin ice.
