If you ever fapped to hentai you've jerked off to drawings of underage girls because 99% of them are underage. I think you meant to say "No man, you aren't getting it. I only jerk off to drawings of prepubescent girls" Unless you actually consider lewding girls like zero two to be wrong too then...I don't know what to tell you man, maybe stay away from anime because it's probably not for you.

Learn the proper meaning of words my dude.

With that out of the way, yeah in a society with such strong negative feelings towards anything sexual regarding minors to the point people attracted to 17yos are called pedophiles even a victimless thing like drawings will be seen as something vile, you can't use reason against emotions but you can try and the reason why lolis are fine is because no one gets hurt, live and let live.
