Saying that someone playing GTA and killing 200 people should be arrested because that shows that they might actually go out and harm a person because they harmed a fake person.
A good point and comparison but it doesn't apply in the same way.
Videogames such as GTA are made with quite literally mindless entertainment in mind. Something as cathartic as violence is simple to recreate in a videogame world, but of course the thousands upon millions of people who have played those games don't have an attraction to murder itself. As I said, violence is cathartic (i.e. doesn't need an acquired taste, it's ingrained in us).
Lolicon, on the other hand, is made to pander to a particular sexual fetish. One that is associated with, and this is the crux of the situation, a disposition with heavily controversial and illegal connotations.
In this situation, they are focusing more on the mindset of the person themself rather than their actions.
