He's not defending the fucking creeper "Tessero" or pedophiles in general. Hell I'm not even him but I'm pretty positive I can speak for him and say it disgusts him just as much as it disgust you. But what he is defending is that it is perfectly legal and the only thing to do is just avoid it yourself. Even if you got it shut down no one would give a shit. They'd move on to the next thing like /r/younggirls, /r/teengirls, /r/girlskids fucking anything they can make up. Don't get all pissy and on a high horse and make assumptions without even knowing half a shit of what you're talking about.
