I agree to your reasons, anime is may be the style of human posture
For most people that anime artstyle could be semi-realistic and Realistic, some anime settings described to be removed by kemono, or others that the anime world known as animated planet earth where real human beings adopted by anime can look more farther than the animation experience.
What do you know when japanese people gets to hate the word kemono known as beast-man, does japan knows that anthropomorphism died from its anime universe?
If so, people challenged to stay human in reality in a anime where a human character portrayed politicaly by japanese men and women by existence of humanity.
