The odd thing is that in the third act of the movie, the alien travels from Mexico into the United States, has a baby, soaks off the American tax payer for free education, housing and healthcare and then kills a couple of kids while drunk driving. When the U.S. military shows up to fight the alien the ACLU and other Marxist groups arrive and demands we call it an "undocumented extra terrestrial" and claims everyone who doesn't want the alien around is a racist.

They can do that because it's fiction and is nothing like reality.*

* - if it were more like reality the alien would also be smuggling sex slaves across the border, raping children in the border deserts and establishing crime syndicates in all major U.S. cities.
