I think Erik was specifically talking about Rantatorials, not overall content.
I for one think most of the Rantatorials should probably be queued up in the normal article queue, with perhaps a header when they might considered a “rant”. I get that keeping the category separate may allow Michael and Kevin to be what they might consider a little over the top from when they write a normal article, but personally I get the fact that this is their site, and they have a right to do that in any article if they choose.
This particular article was well stated and certainly didn’t appear anything at all like a rant to me ... just a well done article with a valuable point.
