I agree. If the person wasn't getting off on loli, he wouldn't have any. Gays don't generally collect playboys -- it doesn't do anything for them.
Actually, for pedophilia cases, most of the time by the time the cops do arrest him, he's been an active (as in actively raping children) for more than 5 years. So, depending on who this guy is, I'd say there are better than 75% odds that a man trying to import lolicon has probably raped at least one child. That's why I'm against child porn. It's somewhat like getting Al Capone on Tax Evasion -- you get them off the streets for possession of Child Porn, and he can't act on his already present fantasies. Or you can wait until a child is raped and taken to the hospital quick enough to get a semen sample.
For those who think that Lolicon porn doesn't mean pedophilia, find me a gay man with playboys under his bed. Then we'll talk. I've never heard of people collecting porn that doesn't address their personal fantasies.
