Well, it’s sloppy at the least. The Pastor did put up a big sign that said “Islam is of the Devil”, so unless he’s pro-Devil, they could call him “anti-Islam”, but I don’t think they should have said “anti-Muslim”.
Yup, back in the day when I took journalism (in high school) you were supposed to just report facts and go to great lengths to stay detached. That has certainly gone by the wayside.
