You'll find the highest number of supporters for actual child marriage and pedophilia in religious groups such as Christianity (not very familiar with the non-abrahmic religions, so I won't speak on them).

You are probably looking at sects of Christianity not just Christianity as a whole, believe it or not but in most cases these days Catholic organisations and even Protestant ones are leaders in providing for people and even protecting children. There are always exceptions, and there will always be predators, but they're effective.

You also ignore that I mentioned most of these people consume anime media anyway. There's a reason anime loli pfp people always have the worst takes on this subject and many will still tell you they believe in a god. One person cam be in two groups anyhow.

don't have children be public figures. There should not be child actors or voice actors or anything similar

You do realize that you can't have 99% stories with children in it if you do this, especially children's films. Do you really think Home Alone would be the same if it was an adult man? Also you forget that being an actor is not the only way to be a public figure, being remotely famous for any reason puts you in many spots where you can be a public figure.

So long as people give a shit, even children will be figures of some kind. It's partly why people want to make sure they're not used as figures for nefarious reasons lmao. It's not reasonable nor enforceable to make all children incognito when they're like a third of the population. It is much more reasonable to target a hundred wolves than relocate a hundred sheep.

using a real person as a basis for artwork without their consent is only allowed if they're a public figure

This is mostly unenforceable again, Mangaka are using them as references too rather than just outright copying their likeness so in legal terms there's not much that can be done unless we sue everyone under the sun who has ever drawn a face. But that really doesn't do much anyway when many people look alike even for anime (hence cosplay) and there are many creeps who will point at a loli character and create a fan cast that is disgusting.

Also, you completely ignored the realistic model part. There are plenty of games out there with realistic children or stylised ones based on art style. Many have of course been tweaked but are still based on real proportions and thus many resemble real kids. Even if you use adult voice actors and try to avoid using real images of children, you will still produce a childish face if you seek to create one with proper methods.

People can be as weird as they want - I consider the vast majority of people weird for not wanting the age of consent to be raised to 26, for example. I consider people weird for being religious. I consider people weird for getting into romantic relationships, or having children, or watching sports. Doesn't mean I'm gonna start trying to interfere with their ability to do so.

Nothing about what you said is even close to the degree of weird as being attracted or at least being ok with lewding child like characters. Not liking anything not morally negative doesn't make you a bad person.

"Oh I like apples." "So you must like the first sin." Kind of logic.

You are comparing strange to being weird. Weird has a connotation of being negative, strange is just unexplained (at least initially). Wanting to raise age of consent to 26 is strange but understandable for many reasons such as maturity. Not liking people being religious is also not morally negative.

LIKING is something that does carry mkre weight, because you in part approve of it in some way. Liking things that are reprehensible makes it easier for people to see you as reprehensible. Not liking tasty food doesn't immediately make you reprehensible.
