I try not to watch pornographic material, but if I do, I watch pornographic material with women my age, maybe slightly younger, but grown-up.
I don't watch "loli", I watch anime and some of them have loli characters. And some of them are really cute, like Kanna-Chan. I don't feel sexually attracted to her in any way, I just like the mixture of grownup-intelligence with a playful character. That doesn't mean anything, my girlfriend is an adult and she is a very playful "childish" person. I like cuteism and sometimes loli characters are cute, not generally and that doesn't mean that cute is connect to young for me. You're really thinking black and white there.
I too think that grooming or any kind of sexual aggression towards children is very problematic because the way it influences the individuals psyche, that doesn't mean that I think all pedos should be gassed. I think the question about this is just a very difficult one. Besides sexual harrasment, what does people make feeling attracted towards children? How can we fix that for society? I don't know, I'd guess they need someone who really needs them to survive. Is that fixable, is that needed to be fixed? Man life is complicated and fucked up, let me enjoy my anime and make your own thoughts about topics. I assume that you have never tried to think, what life would be like, if you found out, you feel attracted towards children. I mean just imagine, suddenly you have the whole world against you. Keep your desires a secret, they are illegal. Everytime I think of that perspective, it makes me realize that our society is not working, just walking.
