racĀ·ism [rey-siz-uhm]
noun
1.
a belief or doctrine that inherent differences among the various human races determine cultural or individual achievement, usually involving the idea that one's own race is superior and has the right to rule others.
2.
a policy, system of government, etc., based upon or fostering such a doctrine; discrimination.
3.
hatred or intolerance of another race or other races.
Read that, and then read it again if you think attraction to particular features is racist.
Can you even state that a person believes all other races they are attracted to are culturally or individually superior to the race they are not? Can you prove that the hate, or are intolerant of the race they are not attracted to? Can you prove that they want to rule this other race?
It is not racism, in any form, no matter how you try to twist it. This question is about preference. Just because a person does not find Asian women attractive does not mean that they believe that their race is superior and deserves to rule over all Asians. It does not make them hate Asians, nor does it make them intolerant of Asians.
Just... wow.
