Although I know that most people here have replied to this post before, I'll reply with something different.
It may seem that liking lolis look to be "harmless" considering it's on the Internet, get this: there could be higher potential for them to do so in real life. Here's an example:
The pedophile shown in the video is
PaulandAmy aka
Paul Rhodes - a user on
Sonic Passion (a site about Sonicfags and their fantasies with Sonic characters erotically or other sick fuck stuff) who is obsessed over Amy Rose to the point of
he thinks he's married to her. He made a video ranting about how he could differentiate fiction and real life:
And look what happened to him now, he's arrested for raping underaged kids IRL:

Seriously, if you are obsessed with underaged kids, drawn or real life, you need some help immediately considering you can have potential to harm some other kids. It may seem simple just to say "Oh, it's just the Internet, I can differentiate that with real life!" but in reality, obsession will become a reality and it will damage yourself too and make wrong decisions. Not to mention that pedophiles are correctly criticised due to their potential for harming kids and do you want a kid to get near to a pedophile?
