Okay. The comment he made that led to the less/well educated part was in an earlier post: "Even with actual bodybuilding (as opposed to strength training), the MA work will supplement it nicely, reducing some of the worst weaknesses. " (I added the italics)
I don't know how you read that, but it seems a little squirrelly to me. It sounds like a pretty definitive statement that MA training will (his word, not mine) supplement bodybuilding nicely. The simple point is that it may not. Depending on what that activity in MA is, it is very possible that it would be counterproductive. I think I said as much in my response.
So, in that context, we get a post that frames this as an education bit, as though this is some bit of esoteric information and not common knowledge. It's like saying, "Some less educated swimmers may not know that water is wet, and as a result, they could try and breathe it. Well educated swimmers are typically aware of all this, and either consciously accept the risk, or do something to mitigate it."
