Reaffirming the Nation's right to deport active gang members is not the issue that makes this legislation problematic. Instead, the denial for gang members to seek asylum and making minors ineligible for Special Immigrant Juvenile (SIJ) classification is.
On the issue of asylum, it should be realized that many members of gang were not willing recruits. Sofía Martínez, an analyst for the International Crisis Group, states in, "Today's Migrant Flow is Different," from The Atlantic that, "...boys from 12 years up are prime targets for recruitment. Girls can also be targeted at an early age, either to be sexually abused or to become gang members."
It is entirely rational to state that 12 year olds are not consenting to a life of gang violence. Often, recruitment comes after threats of violence and through grooming.
This truth also brings the SIJ ineligibility into question. SIJs are those that have been abused, abandoned, neglected, or other similar situations. Minors join gangs out of desperation, or because they are not protected from the threats that force them into membership. Parents are the ones with that responsibility, and gang membership is clear evidence of neglect and even abandonment.
It is irrational to argue that deporting gang members is wrong. However, for those seeking asylum and SIJ classification, destroying their ability to escape gangs will cause more problems than solve them.
