It's called "science", and has nothing to do with politics and everything to do with your statement that humans aren't animals. We absolutely are.
In science there are facts.
In politics there are opinions.
If your belief that humans aren't animals is a political opinion rather than a scientific opinion then I guess this discussion is over.
I, myself, hold no political opinion as to the classification of humans in the animal kingdom. I think that's better left to science, and I think most (logical, thinking) people would agree.
