Looks like several religious organization have gone over to the dark side.
Not unusual, portions did the same during the great wars.
How many going are unemployed, on welfare, or being paid to be there?
They see suffering and poverty and families split, and they want to do something about it. And that's all very laudable - their humanity does them honor. Unfortunately, this is not the right way to go about it.
Making 12 million illegal aliens legal, just like that, may very well normalise the situation, but it also makes a mockery of the concept of American citizenship. It stops being something that those who went before strived for, fought for, sacrificed for, and becomes the equivalent of membership of a "diners club".
Secondly, its a slap in the face to all the many LEGAL immigrants who have had to wait, and pay and suffer the tortous nuances of the US immigration service. Why did they bother?
And its very bad for the judicial system, because it sends the clear message that these immigration laws, passed by Congress, are effectively "optional". Now, if laws are optional, expect more of them to be broken.
