The difference in our society today, especially concerning the way young girls are dressing, shows that the children have been negatively affected. You can't say an 8 year-old wearing a T-shirt with the slogan "pretty pussy" and a sexy looking cartoon girl picture under it is a positive advancement of our culture. Yes, the people who make these clothes in girl's sizes are to blame as well, but someone has to buy them for the kids, and society accepts them wearing it.
What worries me is the level of acceptance we as a society now have to sexually explicit images and behaviour. I am trying to correctly raise my children, boy and girl aged 5 and 3 in this environment, and these images everywhere makes that difficult. It is in their face all the time. I don't want my daughter to grow up thinking a happy girl is one that has large breasts and wrapped in nothing but a ribbon. Nor do I want my son to grow up thinking that women are sexual objects. These images, such as the avatar being discussed, reinforces this. Cartoon or not, the message behind them is the same. My kids like to look over my shoulder when I'm on here, as they like the reptiles pics in some of the avatars, and now I'm finding myself minimizing the screen so they do not see things such as this avatar.
I don't wish to get into the pedantics of what is porn, but this is an image of a happy girl, wearing nothing but a ribbon, and her breasts are bouncing. Like it or not, there is a sexual message behind this, and one I do not wish to expose my children too. Yes, I cannot shelter them from everything and it is everywhere, but I don't like seeing it on a site where I spend a good deal of my internet time, and them seeing it here.
Just my $0.02, nothing personal.
