There are many reasons for Democrats to refuse to allow Trump to build his wall, but I think there's one very big one that people caught up in the day-to-day political struggle shouldn't ignore -- and that is that the fucking thing will stand there as a monument to this low point of stupidity and bigotry in American history for long, long, long after the current historical moment has passed and sanity returns.
Trump will be dead and gone, his moronic base will be dead and gone, the country will have moved on, but the fucking wall will still be there.
And that's what Trump wants, a monument to himself that will be a poke in the eye to nonwhites, foreigners, and libs forever.
He'd probably want a statue of himself commemorating the deed, but even if one isn't erected, the wall will always be remembered as brought to you by Trump.
It's the equivalent of Orwell's boot stomping on a human (nonwhite) face forever.
He dreams of a monument he can leave behind that's going to be part of the country as a whole for a long time afterwards.
So much better than just being able to stamp his execrable name on buildings in cities around the world, he wants to leave it stamped in steel across the entire southern border of the country, imagining it will stand thus for ten thousand years, a forever monument to himself.
I met a traveller from an antique land
Who said: Two million vast and stainless slats of steel
Stand in the desert... near them, on the sand,
Half sunk, an orange visage lies, whose frown,
And anus-like lips, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed;
And on the pedestal these words appear:
'My name is Trump king of kings;
Look on my Wall, ye Mighty, and despair!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.
(with abject apologies to Percy Shelley)
