Cps behaviour aside, in this case of children of illegals, how can it be child abuse if the
children are deported with their parents?  The family is still intact.
We may not like where they are going but the parents are connected to that culture and no
matter how much the children are Americanized you can be sure they were still brought
up in the parents culture.
We can't be all things to all people.  If we try we'll be nothing to everybody.

i agree.
I think if the parents are deported, the children probably should be... and yet I don't know.. I have a lot on my mind lately and probably am missing something b/c very distracted.   

From the US Conference of Catholic Bishops;

"It is preposterous to claim that justice for immigrants isn't central to Catholic teaching. It comes directly from Jesus Himself in Matthew 25, 'For I was hungry and you gave me food…a stranger and you welcomed me.' Immigrants and refugees are precisely the strangers we must welcome. This isn't Catholic partisanship. The Bible is clear: welcoming immigrants is indispensable to our faith.
Caring for and about the 'Dreamers' is nothing more than trying to carry out that seemingly simple, but ultimately incredibly demanding, commandment. It is a commandment found throughout Sacred Scripture, reaching back to the Hebrew scriptures, including Leviticus, 'when an alien resides with you in your land, do not mistreat such a one' (Lv. 19:33). In fact, the Church has been pro-immigration since God called Abram to leave Ur: 'Go forth from your land, your relatives, and from your father's house to a land that I will show you' (Gn. 12:1). To suggest otherwise is absurd.
The witness of the Catholic bishops on issues from pro-life to pro-marriage to pro-health care to pro-immigration reforms is rooted in the Gospel of Jesus Christ rather than the convenient political trends of the day. We are called not to politics or partisanship, but to love our neighbor. Let's reject the forces of division that insist we make a false choice between our safety and our humanity. It is both possible and morally necessary to secure the border in a manner which provides security and a humane immigration policy.
Our pro-immigration stance is based on fidelity to God's word and honors the American dream. For anyone to suggest that it is out of sordid motives of statistics or financial gain is outrageous and insulting."

I agree the bible tells us how to treat a stranger in our land but it seems the bible is talking about strangers one at a time not tens of thousands.  That's close to an invasion.

Was Aguinas' thoughts on immigration against the bible?

^{From Paul's Letter to the Hebrews;
2} and remember always to welcome strangers, for by doing this, some people have entertained angels without knowing it.
