my original point was about the origin of gl as a translated term but i understand if it's fallen apart at this point. ie shoujo ai (devoid of context) -> girl's love (in the west) -> back to gl in japan. if that makes sense. basically it's a game of telephone
ok i concede on the point of its original meaning, however you can still go on pixiv and find thousands of illustrations by japanese artists tagged GL. so.
what? what are you talking about. that is not how the word is used at all. even if that were true there is no indication that it's purely underaged girls x adults. girl's love (love between girls) is as literal a translation as you can get
