Well, I dunno. I think she tries to go to some length to differentiate H/Hr shippers and the hardcore 'Harmonians'. I think that sort of name lends itself to a sort of cultish kinda thing, which definitely doesn't explain the majority of H/Hr fans. I think the difference, essentially, is that Harmonians have turned H/Hr into a religion, pretty much: their beliefs centre around JKR writing a romance that should act as the moral benchmark for all other romances. It also kinda goes along with this weird idolising and exalting of Harry and Hermione, often to the detriment of the Weasleys or anyone else.

I'll go have a look at your entry.
