"There will be a lot of illegals here if they don't let the children be citizens"
Uh - there aren't already?
What's the logic here?
It's a threat. The lady is threatening the country with that remark, trying to emphasise the persistence of people from wherever she identifies with in breaking immigration laws: no citizenship for their children that illegal immigrants birth here, who cares, they'll be here and give birth anyway.
I also think her statements otherwise are offensive: people who work hard also break laws and aren't exempt from reprimand just because they work hard (I can think of many examples of criminals who work hard, and otherwise, hard working people who break laws -- one does not cancel out or prevent the other); her son because he's "legal" can "come and go" across our border/s "freely" instead of ongoing illegal activity (which she's also acknowledging, glad her son no longer has to, glad she doesn't...but the point is she's emphasizing that they're 'coming and going' without regard for any goal of citizenship in the U.S. in regards to embracing the U.S. as home and culture); and, her own enrollment in Medicaid, thanks to her son being granted citizenship by birth here to her, an illegal alien in the country.
It's generally terrible character and just being a mother/parent to anyone doesn't excuse it.
I agree that the "citizen by birthright" if/when someone is the child of illegal parents or a parent has to stop. It's the reason that many, if not most, arrive here illegally with the intention of being able to remain after giving birth, and most do that, too.
