> The idea that illegal immigrants need to be deported comes from a view that those jobs should go to American citizens or from a view that browns don't belong in the USA.
Or, you know, from the idea that they are doing something illegal and the job of law enforcement is to enforce laws.
Laws aren't moral. These laws are bad, and shouldn't be enforced. They should be changed, but we don't have the political will to do so, so "rounding up all the brown people and shipping them to Mexico" is not the second-best option.
It's actually not a crime to overstay a visa or to be here without one. It's nothing.
It only becomes a crime once you're formally deported
