They are right you are not

You have no room for mistake when it comes to child porn or sexualisation of children photos they are completely right to be paranoid, you only need one mistake to have your life ruined this is not a shoplifting crime that you can recover from after being caught, a couple of wrong photos or wrong comments and your life is ruined, being outed in the public alone will likely leave you jobless and homeless even without a prison sentence. You say there is nothing wrong with certain pictures but this is a world where people are sent to prison over cartoons and even fiction stories involving child sex, just because you see nothing wrong it does not mean others they won´t, anything to do with children being used for sex, at a fiction level, dressed cute pics or whatever it is going to revolt and disgust people they are going to want your head on a plate, this is not about wrong or right, this is about if they can get you they will, nobody cares that you did nothing wrong.
