It's not so much that I fear calling her out by name (outside of a possible superstitious Beetlejuice-inspired outcome) that I'd just rather avoid any possible conflict, because those debates on FFN really are a nightmare. And this is coming from someone who's never interacted with her before. I was considering blocking her already as a precautionary measure before, and after hearing this I think I kinda want to seriously consider doing it now. Just to spare myself the grief, because the last thing I want to do is try to communicate with someone who will only bother responding with multiple emoticons or otherwise just not take anyone seriously, because evidently in a debate it's all about her and absolutely every point of view is invalid except for hers.
People like that are just completely a waste of time trying to get through to. Doesn't matter if she's "right" and a competent writer herself. Like I said, the capitalization thing should be a "to each his/her own" thing since there are perfectly logical reasons to use either or. As long as your general grammar/spelling is in check, to me this is more an issue of style than it is accuracy. While it screws with me visually to see Pokemon terminology not capitalized, it's not something that completely impedes my ability to read a story. I like to think it's the same the other way around, too. There's really no need for a right/wrong in this subject at all... just preference.
That said, I don't really have any ideas at this time about settling on a name for the term. Some kind of word that collectively covers how all official Pokemon media use this convention for fictional species, items, and other Pokemon-related lingo... trickier than it looks.
