I'm a little confused, Rock.
There's nothing to be "gained" by meeting with these particular ministers...presumably because they are what is considered "alt-right"?

But I don't recall seeing any such analyses or conclusions when the Pope meets with more liberal minded ministers...say, the Archbishop of Canterbury or the leaders of the Lutheran Church in Sweden. 

Why the distinction?  Or is it only beneficial to meet with folks with whom the Left has a more ideological alignment?  
That leads me to believe that talk of "dialogue" is merely smoke and mirrors...is it?
