I agree with that. But whether the character is a loli or not is based on author's intention. Lolicons will sexualize a young girl character whether it's a loli or not.
The sexualization doesn't even have to be overt. The character basically just has to exist purely to provide service to Lolicons. I think a character like Wendy in Fairy Tail is an example of this. I don't think that character would exist in that form if Mashima wasn't trying to check off boxes on a list of target audiences.
