I believe you, no reason not to. I'm sure that's a valid reason.
Though I still wonder why all the anime pre-teen chicks. There's a lot of goofy guys in anime. Yet you don't see them as avatars nearly as often. I'd could also go into why it's mostly a Japanese thing and in western cartoons it's usually the other way around, or was up til recently but I'm more interested in say why someone like you picks the pre-teen girl instead of the pre-teen guy.
But as I said, even the majority of people who are into clearly sexualized adolescent anime aren't pedo's but have other reasons for liking that stuff and I wouldn't put that character of yours in the same basket anyway.
For example, although I've never watched a full episode, Girl und Panzer is a bit of a guilty pleasure of mine to open up on youtube when Im bored and just watch a scene or something or the song that's kinda funny. And when I've asked myself why the fuck I watch a nonsensical cartoon with a bunch of chicks in tanks I think it's because I used to be a bit of a history nerd, there aren't a lot of women interested in or even part of that type of history and so it probably fills that void. I have no idea, but I know it's kinda fucked up and it's a stupid ass show that doesn't make any sense nor has any good writing if I'm objective about it. The scenes I've seen aren't even that funny.
