Sorry to hear your PC crashed. If there's more we can get to that.
So, here's how it is for me:
I totally agree there's nothing about micro or macro that's inherently sexual. They're totally valid prefixes for lots of words, like microscope, macroeconomics, and so on.
However, when it comes to character size, it is only really used in sexualised contexts where the individual's size is the subject of a fetish:
- Micro isn't commonly used to refer to action figure sized people. Tinkerbell isn't described as micro in kid's books, she's described as tiny enough to stand on your thumb. She's micro when we're doing sexualised size play.
- Macro likewise doesn't get used to refer to giant people.
Now, you're referring to Google and D&D. I'll respond to those.
- Google avoids showing porn. Look up "facial" with the filter off and you'll probably see women getting beauty treatments. You found chibi figures for micro - fair, but not, I'll note, action figure sized people. You found fonts for macro, but not, I'll also note, giant people (except for that one featuring a prominently features a bulging crotch). Google is not going to be our arbiter on how these things get used. Go look at PG books and you won't see much mention of it. Go look at a place that exists for artistic and writing smut, and you'll find them used as the key words for size play-oriented smut.
- D&D, and other similarly meticulous games like GURPS, have to pull out a thesaurus and chop and change arbitrary words to find right-sounding words to fill out their size charts and other similarly detailed lists. I'm not taking its usage of "micro" as an indicator that anyone uses it that way outside a particular classification inside D&D.
So my issue is: we're using terms that are well-defined and used this way for character sizes in smut sources. We're relying on people being familiar with smut or looking up a smut glossary (which is the only place you'll find a definition of macro/micro for character sizes that matches how we use them), or teaching them what they mean in smut and inducting them into smut. If we want to present ourselves as a site that's amenable to maintaining a barrier between PG-rated content and smutty content, we should be keeping smut terminology outside of the PG-rated side of that barrier. Which means we shouldn't use micro/macro as our terms for these character sizes.
Maybe tiny/miniscule and giant aren't the best words and we can do better. I'm open to suggestions. But micro/macro are words we absolutely shouldn't be using here. It's not appropriate.
