"Pope Francis exhorts listeners to overcome the fears that drive people to seal themselves off from others."

But Holy Father, one has to acknowledge that Europe's fear (if one wants to call  it that) comes after an actual wide-ranging global experiment is taking in massive numbers of peoples from different cultures.

That is, Europe began with NOT "fearing" the Other, and gave the Other the benefit of the doubt in a spirit of generosity and fearlessness.

The results of that experiment are directly reflected in current European opinion:

Not even one European nation has more than 20% of its people strongly for what you want them to do.  

Perhaps the fear in these liberal nations has much more to do with experience than with blind bias.
