This is Anne Coulter PMS-ing, and trapped in a closed loop of her own intellectual hoo-haw.
We do need a wall, why? because there is a chance that we again will have a treasonous lefty liberal fascist president like Obama the magic negro was.Walls work. Both physically and politically. This has been the case throughout history.
The other option is to annex Mexico as a territorial protectorate of the United States, like Puerto Rico. If Russia can do buffer states, so can America? The wall is a better alternative IMHO.
Yer onto something, we need to bust Mexicos balls!
Corrupt bastards make their poor OUR problem.
