what i dont understand is as a species we pride ourselves in collecting unique things, plants and animals. we love the different colors, sizes, shapes, and strange features such as two different eyes or no tale. but we recoil from any human who is physically, mentally or even sexually different then us. the only reason my black domestic cat doesnt like my blue manx cat is because she is old and grumpy not because she doesnt like how my other cat looks. i just dont understand this. how can we prize differences in other creatures but not humans?
