This is a more detailed explanations of http://antiwesterncosplayers.blogspot.com/2015/11/the-best-response-to-show-how-retarded.html
There are 2 best responses when you see any of the racist westerners who claim that the Anime characters we Asians made with yellow hair and blue eyes as of being based on those westerners
1. Ask them about what race are the cosplayers who have yellow hair and blue eyes in this video
If they answer them as westerners then that just proves that they are retarded because any sane peoples will answer them as Asian. If they answer them as Asian then that also proves that they are retarded because of the logic they use where they recognize peoples race based on peoples hair and eyes color are just retarded logic. As you can see in the video having different hair and eyes color will not make someone race change into another race, the same with the Anime characters we Asians make where their appearance still based on our Asians appearance no matter what colors we make their hairs and eyes are including with yellow hair and blue eyes, you can clearly see that the appearance of our Anime characters with black hair, yellow hair, black eyes, blue eyes, etc are typically look the same just like how we Asians are no matter what hair and eyes colors we Asians have our Asian appearance that makes other race recogize us Asians as Asian are still look the same.
Talking about our Anime characters hair and eyes color, the big majority or over 98% of our Anime characters have black hair and black eyes, as for the less than 2% does not automatically mean all of them have yellow hair and blue eyes because we Asians not only using black and yellow for our Anime characters hair or black and blue for our Anime characters eyes but also any other colors including red, purple, green, etc any other possible colors. This mean that by default [ as a result of the over majority numbers ] the default race of our Anime characters are Asian, so any of our Anime characters including with yellow hair and blue eyes who have the same appearance as our default Anime characters will mean that their race are Asian or will mean that they are based on us Asians.
2. Ask them about the same characters but from the Manga if they still claim them of being based on westerners or not
The same as before, no matter what answer they have will only proves that those racist westerners are retarded. As you can see the appearance of the same of our Anime characters who have yellow hair and blue eyes in our Anime still look identically the same as in our Manga where they just have black hair and eyes. This proves it more that hair colors and eyes colors mean nothing to our Anime characters appearances or no matter what hair and eyes colors we Asians make our Anime characters with we Asians still make our Anime characters appearance look typically the same which based on our own Asians appearance.
As for the actual reason of why we Asians make our Anime characters hair and eyes with any possible colors including yellow and blue are explained in more details at http://antiwesterncosplayers.blogspot.com/2015/04/asians-are-smarter-only-asians-who.html
