There is no aregument that people percieve pirahnas as blood thirsty killers. My argument is that the best way to change that perception is not through hiding the pirahna. It is through educating people about the truth about them. How are you going to teach someone about an animal they know nothing about by hiding that animals behavior. Its insane to think that your methods would work, and as insane to think that if you were to bring more poeople who agree with them that would make them any better. The truth is you cannot change someones mind about anything by hiding the truth.
