althought it is a good example to differentiate things, it isn't the same.
as desire is a different thing and is part of human nature, and watching some things can unlock some "triggers" in people.
violence, murder, blood and other things have a grand impact on children and the way they act, althought adults know better to differentiate things it cant be said that nothing changes in them( from person to person the dregee change).
i'm not ok with pedophilia on videos or anything that include it, i comndem it, and think about it, if a person watch hentai with pedophilia they have desire for it, althought it isn't "real" but it can have influence on a porcentage of those who watch it to do the real thing, some will stay locked in the room watching that shit, and some will have vile and evil thougs about doing it in RL.
studying about humans, their thougs and how they act and change is usefull when looking at humans( althought it isn't 100 precise and have some exceptions).
hentai and desire is ok.
pedophilia and desire for it is sick.
i won't protect him as he is generalizing.
but me, myself would only consume things that i has deside for, if i desire chocolate or food, i ll search content of it, buy it, or make it, if i desire to be sad or happy, ill do things or listen to things that make me feel this way, can you do things without desire( like playing games that kills, rob, have war and blood without wanting to do any of this)? yes, but i think that it is different for " carnal" and i forget the other word in english, none would search for sexual shit without desiring it
