"Pro-life" is a euphemism for being against laws that permit abortion.  Using the term for anything beyond that definition is propaganda and disingenuous.  The DACA issue is about much more than just families; if you want to apply a label for Trump's position on DACA, use something like "Pro-law enforcement," because that is the issue: people breaking the law.  The President's job is to execute US Laws.  Quite simple when you cut through the spin, isn't it?
