I'm the dumbest man alive

If the character is under 18 years old then it is child pornography. It does not matter if it is fictional or not. (Watching any kind of pornography is not good)

actually loli of any age, kind or whatever is CP

Exactly.

Like the mom from masamune kun no revenge

honestly I hate it whenever they sexualize the cute short kid looking characters because whenever i see one in an anime for the first time i'm all like "AWWWWW look at the lil tiny thing!" then about a couple seconds later they let out some sort of weird comment, or the anime portrays them as sexy in some way

Like when I saw this character in jobless reincarnation, i thought "AWW aren't you just ADORWABLE" and then a second later she tried to take off her underwear and i was like "sigh...yep that rolls more in line with this anime"
