This was a beautifully shot piece of socialist propaganda. You can't build a wall, because they like having free access to another sovereign country's land dammit! I mean look at us.. we are swimming in water and laughing and playing heartwarming music in the background. What more could you ask to leave the border wide open? These people have feelings! I'm sick of these puff pieces full of questionable science and no legal or substance based argument of any kind.
