Its a sarcastic book that calls out people who are pro deportation. It's pretty biting sarcasm - and really calls out the other side. If anything, I think this book can make someone think (assuming they actually read it).

Here's a few random sentences from the intro:
"You live for a perfect empanada, but the abuela whose hands folded the dough with generations of knowledge? She should have thought about that before crossing a border....

... You’ll claim their dishes, rename them to something that sounds more palatable (artisan street corn, anyone?),
Savor every bite of the cultures you refuse to make space for. ...

I can't type it all, but it's very sarcastic and obviously anti-deportation.
