My point was to emphasize that "common sense" is not some particular theory which is, or was, popular among the people. Like in "common sense to people at one time was that things need to be pushed or they stop moving. Newton's first law changed that - at least for anyone with basic education". This is not what I would name common sense. Already for the simple reason that it is not common at all, but a particular theory. As the old one, as the new one. But this identification of "common sense" with particular theories which have been popular is quite common, and used to discredit common sense, using examples of some quite stupid theories which have been popular some time as evidence against common sense. I have seen in your post an example of this, that's why I have answered.
