I know what you are getting at but I am just confuxificated about the psychology behind it.
Okay, we all understand at least their concept that PETA propounds that we should be kind to animals, that we should not harm them, that killing them and eating them is not kind. I myself sell a handmade soap that I tout, "no animals harmed in making my soap." I use purely vegetable oils. Think Etsy if you wanna think me out. I like craft hobbies.
But in anime or cartoons, exactly which children were harmed? At best you can only argue that it encourages pedopiles to continue and escalate. To that I have no argument, it may be true. It's the same mind set that milk use leads to marijuana use leads to heroin abuse.
I'm not interested in CP cartoons, but I question just where the line is.
