Theoretically? Maybe.
In practice? Far too much of it is tied up with oppression, basiclly. Giant women oppress tiny men (apparently, generally desired by men), while giant men oppress tiny women.
The thing is, GTS is acceptable, which is probably why most size content you see in commercials and the like is GTS, but GT/sw gets far too close to a lot of social issues to be acceptable.
Though, there’s also the fact that being openly furry in public is… easier, for lack of a better word. All you need to do is wear an (apparently expensive) suit to be a furry. If you want to be an SW, what are you going to do; wear a giant hand around you? If you’re a giant, do you need to attach Hot Wheels or tiny buildings to your shoes?
and just kinda wince.
