What are Greensboro's conservative publications afraid of?

Five days ago, I submitted the following comment to a story at the Rhino Times website:

John Hammer impugns Eric Townsend by saying Townsend reported something that "wasn't true."
Yet, Jerry Bledsoe reported the same thing, in the Rhino Times no less.

My comment has not appeared; nor has another submitted by Jeff Martin. I cannot confirm, but I'm told several other comments, submitted by others, also remain hidden. A single innocuous comment has appeared, so it's not a technical issue.

The Rhino's website advises that comments will "be reviewed by our staff before appearing on the website." This is a practice shared with Greensboro's other conservative publication, The Greensboro Guardian. Like The Greensboro Guardian, it seems as if the Rhino Times uses this method to squelch comments they find inconvenient.

The News & Record does not subject comments to pre-approval. Neither does Yes! Weekly, WGHP or WFMY. What does it mean that this practice is confined to Greensboro's conservative publications?

Yesterday Two days ago, I sent an email to Rhino editor John Hammer and asked why my comment has not been approved from moderation. He said he'd look into it. I haven't heard back and no additional comments have appeared.
