The refusal of the author to describe the difference between the two (while expending so many words to emphasise that they are different) is a bit odd. Especially as Lolicon is a relatively well-known term in the English-speaking world, and is even derived from an English-language/Russian-American-written/French-published book.
It sounds like the author would like to use stronger, more direct words but is skirting the issue to avoid apparent bias (though the bias is really quite apparent) and ends up sounding vague throughout.
The author does an absolutely great job of describing the actual subject which is the devision and different perspective. This is not an article about the difference and if he went into any sort of detail it would only deraile from the actual point of the article which is that there are two different perspectives on the same thing and that the people involved in general do not understand the other side.
That's certainly the author's thesis: binary division, lumping a spectrum of opinion into two diametric extremes. It's a popular narrative and rarely, if ever, representative. It would be much easier to assess how true it is in this case if there were any insight given into the issues themselves.
