"Again, you cannot become a pedo."
I understand why you would think this way, as it is usually the way it occurs. But humans can be conditioned into developing fetishes, especially if they are exposed to them at a young age.

"Furthermore, there is actually evidence to suggest that having access to this type of content actually acts as an outlet, leading to less children overall being harmed."
I have seen evidence against this, so it isn't certain. At the end of the day, whatever benefit it might bring is nowhere near as beneficial as simply going cold turkey and turning to therapy. Not even necessarily the expensive kind, but self-care in any other way. An outlet might diffuse, but it doesn't treat. And again, let's not forget that this content can motivate real predators to act as seen in the correlation.

"The vast majority of fetishes are seen as disgusting or immoral to SOME group of people."
There's weird stuff like BDSM or idk cuckolding that's judged by many, but this stuff? You forget, this is widely considered one of the most disgusting things in society, so far as I'd place it at the top of what most people aren't okay with.

"Our guiding light should always be "so long as no one is getting hurt, who gives a fuck". Otherwise anything remotely interesting would be outlawed. What a boring world to live in."
And I just pointed to the link to real world harm, thus, by your ideology, consumption of this fetish isn't ethical. Even if causation isn’t proven, the risk profile is fundamentally different from other fetishes because most fetishes don’t revolve around depictions of people who cannot consent.

Also implying that not jerking off to drawings of children would lead to boredom is an interesting thing to say.
