babies and toddlers of immigrants crossing the border illegally are being separated from their parents in the hundreds. We have no evidence that these parents have been charged with violent or other crimes of a nature that might justify the separation for the children's safety.When parents commit crimes, they are going to wind up being separated from their children. This is a consequence of breaking the law - you commit a crime, and then you go to jail. Your children can’t be with you in jail, so you get separated. The evidence that they have committed a crime in the case of illegal entry is by default - they couldn’t be arrested by the US border patrol unless they violated the law, because the US border patrol doesn’t arrest people in Mexico, they arrest them in the US.
So, in order to support these parents not being separated from their children, you have to support not prosecuting people for illegally entering the country. That, by definition, means you have to be in favor of illegal immigration.
