This has NOTHING to do with the refugees. These radical groups are the reason they left in the first place!
A couple hundred people, some of which were French citizens, left to become radicalized in Syria and were seemingly allowed to return. A few orchestrated these attacks, but that's a disgusting radicalized few.
If a Trad shoots up a synagogue citing St. John Chrysostom's adage about the Jews, the media would have your EXACT mentality, if not worse. So do not assume things, but simply pray for the Eldest Daughter of the Church.
The liberal delusion in the above person is strong. I feel like he is reading a cnn talking points bulletin. If he has any daughters, he should just give them to the refugees. It will be easier that way.
