".... a recent study by ..., a Georgetown University research project on Islamophobia, showing that Catholics who regularly obtained information from Catholic media were more likely to unfavorably view Muslims than those who did not"

This is sad, but not surprising. Too much of the American Catholic media lean to the far right, happily following Trump down the "all muslims are terrorists" rabbit hole, repeating non-facts as "truth".  My EWTN -type Catholic relatives were shocked to learn (from me) that Muslims are only 1% of the US population. They believed that if they didn't vote for Trump, sharia law would be just around the corner, that there is a Muslim plot to take over. 

 Due to the heavy hand of censorship in the Catholic church, only a few in the Catholic media are able to present broader views - NCR is one, Commonweal is another. Both are run entirely by lay people and cannot easily be silenced or  censored by bishops.  The Catholic church has never liked a free press.
