Why Charles Davenport, Jr. is insulated from comments at the News & Record

I emailed (Greensboro, NC) News & Record editor Allen Johnson to ask why comments were allowed on every column, editorial and letter on Sunday except for Charles Davenport Jr.'s. Here is the entirety of his reply:

"We as a general policy don't enable comments on racially sensitive content because the comments tend to get ugly and out of hand."

Update: The facts collide with Johnson's explanation. In the past month, there have been three editorials about race, each had comments enabled.

• "Take a direct approach to racial justice" -- by Doug Clark
• "Being safe rather than sorry" -- (An unsigned editorial about reporting on Nazis)
• "Greensboro is a poor location for Neo-Nazi gathering" -- (An unsigned editorial)

I could find no other columns about race in the past month in which comments were NOT enabled. Davenport's appears to be the only one.

Update II: Allen offers as a subsequent explanation that the N&R does not allow comments on columns by freelancers, also contrary to the facts, as documented here.

Update II: On his third try, Allen says, contrary to the examples above, it really is that they do not allow comments on columns about race... or sex.
