It is like saying one is a fact and the other is an opinion. I feel dissection is mindless‚ disgusting‚ and torcher to animals of all kinds. It makes me feel light headed just hearing about it or thinking about it. All of the small animals such as frogs‚ insects‚ gerbils and other small animals being dissected are helpless
