This was true, although it's hard to take notes when people are speaking in unknown tongues. I have been grilled by New Agers, United Methodist bishops, legions of Episcopalians, every manner of rabbi, assorted Calvinists and Baptists, both northern and southern. A public relations pro in Salt Lake City once assumed I was a Mormon because I have a strange beard and kept waving away the waitress with the coffee pot. I propose a moratorium on asking journalists the church question. There isn't a really good answer to the church question.
Few people love traitors.
It may not help to say you attend another church. Some people will then assume you're an apostate or that you'll be prejudiced against their church - or both. If you decline to answer, this also makes some people mad. This says, in effect, that the interviewee has to open up his or her soul, but interviewer does not. And it doesn't work to say that it doesn't matter which church you go to, or whether you believe anything at all, because you are a professional journalist and, thus, you'll be fair to everyone.
