Nobody's trying to convince you of anything other than the new Gelato being able to pass as a young adult, something your inner issues don't let you accept. We aren't playing devil's advocate here, she
is meant to look young. The whole Steam thing might as well be completely made up, but
suppossing they did greenlit the current model, that backs up our point as well.
For real, tho; look again at the preview... She's got that waist to hip ratio, long legs, and meat where a sexually mature female usually has. Except it's not exaggerated like every other model.
Your standards are your prerrogative, just don't try to bring them as universally valid because they clearly aren't. Had you said that Gelato was not to your liking would have been perfectly understandable; trying to put you as morally above people that like her because of some absolutely subjective considerations is where you failed. At this point I can safely assume Marie Rose makes you vomit?
Tripling down on your fuss because of some petite female cries for real self inspection. Surely I also have matters where I need to improve myself, but other people's preferences and paraphillias certainly are not of my concern. As long as they keep to themselves and do no harm, it's perfectly inconsequential for me.
