I'd say loli hentai is actually more distilled, visually appealing, action packed and addictive version of child porn, and long term it affects consumer's perception of real-life children in a deeply satanic way, and as such deserves more stigma than it gets.
Wow, this virtue signaling thing is easy.
To be clear, I'm not advocating for loli hentai or CSAM. I'm closer to the ban Internet porn side of things. But it's not because I think it turns you into a degenerate (I'm on a big "please interact directly with more humans" kick lately). While it's true if you're sexually inexperienced you get a weird idea of sex from porn, it's not as though you watch a lot of, say, stepsister porn and dot dot dot, a few months later you're propositioning your own sister. These are the same wrong arguments people made about video games, horror movies, whatever. It's moral panic, pure and simple. And anyone who doesn't think that should explain why it's illegal to have CSAM but not snuff, why it's illegal to generate CSAM but not pictures of people being murdered, etc.
