Why do the ignorant insist on ruining a legitimate debate?

i honestly believe that in this world not all humans are "human". i'm not talking about aliens or anything like that, just some people can relate closer to animals and that mental capacity than those that are truly honest, noble, honorable, reasonable and most importantly loving, conscious beings. look up the "gom jabar human trial" metaphor from the Dune novel, it will help you understand my meaning.
