Self-righteousness and ingratitude are sins, too, ya know

Lauryn Hill, a singer whose oevre I am completely unfamiliar with, denounced the Church’s leadership at the Vatican’s Christmas concert. Maybe someone can explain why a non-Catholic was performing at the event. I know nothing about the her, except that she’s made some pro-life music in the past, which I assume is why she was invited in the first place.
I don’t agree with the stereotype that says Americans are all insensitive boors who are eager to share their ill-formed, ignorant views on many topics, but it’s not hard to see where that opinion comes from.
