My standard answer to this:
That guy played the “children” card to show Trump as heartless. Trump said he’d build safe zones, would take care of refugees just in their own country.
Meanwhile, San Bernardino couple abandoned their 6 month old baby to go on a killing rampage. What kind of parent does that?
Terrorists, that’s who does that. Kids don’t exclude terror.
The civilized countries in the world neither have the space nor the resources to take them all in. Particularly when 80% or more are military age men who leave the women and children behind to deal with whatever it is that they are fleeing.
