That wasn't a disgruntled worshiper shooting up his own church. It was a man who was unemployed and having difficulty finding a new job, using his bigotry against liberals and gays as an outlet for his bitterness and frustration. He shot up that particular church because he felt confident he would find liberals and gays there because of some coverage about that church in the news media. Carlin may have had it right, but he wasn't talking about this kind of situation when he said what he did about disgruntled worshipers.
