I don't know why people get triggered by this image, its just a girl sucking a lolipop.
What, are you angry/uncomfortable with this pose? Are you going to say that this is bad because it looks like something you think is bad?
Why not consider telling the girl that what she is doing is similar to a sexual activity which afults will think that way?
What if thr girl did it on purpose? what if she knew and took a selfie herself with this pose? You're still gonna find someone to blame, like "oh, some man made her pose like that, that pedo!", or "omg she was raped" because you have been brainwashed to think that lolis are all pure and innocent and any stains are caused by A MAN LOL XDDD.
What will you do if a loli sends a naked picture to you? Go to jail by confessing to the cops you had seen loli body? Oh wow, that was really abusive and traumatising, lol xd
