All of the Chaldeans I have read about being deported have criminal histories, usually extensive one.  I suspect very few people decrying this deportation are familiar with the Chaldean Mafia.  
   It is easy to fall prey to the "poor Chaldean Christians" being "persecuted" by deportation mentality, but the U.S. have a population of over 300,000 Chaldeans, the vast majority of whom are peaceful and law abiding and who, consequently, have no concerns about deportation.
   However, the predators who are NEITHER peaceful NOR law abiding SHOULD be deported.   Furthermore, these Chaldean criminals tend to victimize Chaldean communities.
   Defending such criminals because they are "Christian" or "Catholic" is akin to defending the KKK because its members are "Christian".  Unfortunately, the KKK are American citizens so we can't deport them.
