Secondly, the book they're featuring on that image is a rather significant entry in the literature of liberation theology. There are a number of footnotes citing Marx and Engels. Communists haven't been known as the greatest defenders of intellectual freedom in the world. Just ask George Orwell, or Aleksandr Solzhenitsyn, or Blessed Pope John Paul II.
But I do urge you to read Freire's Pedagogy of the Oppressed. And find out who's taking it seriously. Then ask yourself why people might find it problematic. I don't support banning books. I don't support destroying books. I do support intellectually dismantling certain systems of thought.
For a very interesting reading experience, try Freire at the same time as Fr. Richard Gilsdorf's Signs of the Times: Understanding the Church Since Vatican II. It was an eyeopening experience for me.
