I just love it when someone announces X is not the answer, but doesn't provide a solution. It is SO simplistic. The border fence is fine.
The Bible does NOT say -- 'and when they get to your land, make sure they get welfare and medical and HUD housing and free this and that. And don't worry if they drive without a license or don't get insurance; it's not fair to ask the poor and downtrodden to follow LAWS.'
I think it's time to assert the separation of church and state issue. The church - any church - cannot tell the state how to run the country.
I believe that is one of the Commandments. Perhaps the Catholic Church should be counseling the illegals to quit coveting out country.
