Mexico and other South of the border nations aren't lands of Christian community?    The Catholic church doesn't exist there?   

The claim that this issue is about Christian values is a huge canard.   This crusade to bring poor people into the U.S. began in 1965, with Kennedy, as a means to change America's demographics and flood the democrat party with new voters.   It has nothing to do with "Christianity,' but everything to do with politics and leftish ideology.   And for certain American bishops, it's also about building church membership numbers and revenue.
