Here in the USA, Trumpists are very hostile towards immigrants coming from the Mexican border to the point where they infamously proposed to build a wall. The Biden administration is better in-name only, and has kept the concentration camps at the border.
Why is there so much hatred toward these immigrants? What is the material cause of this?
Do you want an actual answer from someone who actually voted Trump and supports the wall and deportation, or do you wantbto circlejerk?
OP asked for a material explanation.
If you voted for Trump and support the wall and deportation, and you have a material explanation for that, then just post it.
