Sorry you were offended, but you need to know a little something about the blogging world.
I've been doing this for a while, so I speak with some experience.
Those who seek to hide themselves by anonymity by commenting with a "nickname" or just anonymously, tend to have something to hide. The person is a trouble-maker or is running from some sort of accountability. In honestly, it shows a profound lack of respect to the person's they are commenting toward.
I don't usually suffer anonymous individuals who have no profile page where there is something a little bit about the person, who they really are, where they attend church, where they live. Especially if they are accusing me of shepherding crimes of bullying congregants.
That isn't asking for much. I just want to know where the person is coming from, because I am in fact responding as a person to a person.
Another issue is that I am now dealing with on the blog is people from other churches who have dealt with abuse in their own church. Some have e-mailed me privately telling me their personal accounts of sexual abuse that was ignored, overlooked by leaders in the church. I am not about to expect them to reveal their identities and re-victimize their children who have already been abused. Even the media does not do this.
