Yes, it absolutely is his responsibility to understand the problems he wishes to pontificate on (shameless pun intended). To do less demeans the Papacy. To say that the West needs to love their neighbor and the stranger in the context of immigration/migration patterns and all of the political problems they create, for example, is simply inane. His problem is that at times he only perceives things through an ethical or moral lens when it's 1) simplistic and 2) not always appropriate.
