"Yet in those two years, the appreciation for this document among the Catholic faith community is not entirely evident."

Are we talking about the Catholic faith community throughout the world or just the Catholic faith community here in the U.S.? Because it seems entirely evident to me that the half of American Catholics who voted for Trump have a vested interest in ignoring both "Laudato Si" as well as any empirical evidence that affirms the truth of man-made climate change, all so they don't have to confront the truth that they have enabled the continuing destruction of the planet vis-a-vis their votes for Republicans, who are all in bed with the oil & gas and coal industries. The other half who voted for Clinton have no representation in the episcopate so it's as though that half of American Catholicism didn't exist. Perhaps that's why Catholic attention to LS is not entirely evident to this author.

People routinely ignore that which they'd rather not confront. No mystery there.
