Long ago, during one of the Key West, Fla., "Faith Angle" conferences run by the Pew Forum on Religion & Public Life (click here for amazing transcripts), journalist and digital maven Steven Waldman made an interesting comment about online trolls. The goal of those gatherings was to inspire dialogues between scholars and mainstream reporters about religion and the news. Needless to say, changes caused by the Internet were a big part of that.

Waldman is best known for his work as senior advisor to the chair of the Federal Communications Commission and, before that, as the co-founder and CEO of Beliefnet.com. Especially in its early years, Beliefnet was precisely the kind of place where journalists were, for better or for worse, banging their heads on the emerging realities of Internet life.

Everyone learned pretty fast that things could get really hairy (troll image, of course) when you threw open the comments pages on sites focusing on religion, media, politics, social issues, etc. Clearly there had to be some rules. One of the rules Waldman described to me that night in Key West came up during this week's "Crossroads" podcast chat with host Todd Wilken. Click here to check that out.

Anyway, Waldman said that one of the key rules Beliefnet staffers used when encountering fierce opinions in the comments pages went something like this. You could leave a comment that said something like: "According to the beliefs of my faith, I think that what you are saying is wrong and, thus, you could end up going to hell." That was strong stuff, but acceptable. Otherwise, the site's editors would have been saying that believers in traditional forms of some major religions -- Islam and Christianity, for starters -- would be banned from talking about core elements of their faith.

But here is what believers were NOT allowed to say in the comments pages:
