science is the study or observation of etc... Etymology is the study of words and their historical derivatives etc etc... You are correct in stating the linguistics aspect of this, but you are misconstruing the point. Etymology is a science because you are studying, gathering information to make it relevant to whatever the circumstances may be.
Add on: You are the only one w/this erroneous assertion of Black people having the ability to be racist. It is bigger than me not liking someone based on their ethnicity, that's called pre-judging someone. Nettrice eloquently responded to this post stating it is all about power! I have to concur w/her assessment. So now on this note...

“...This is why I shall continue to labor and endure the strong currents of spirituality, the manifestations of which are health, purity, and self immulation, must deepen the human experience; until the beliefs of material existence are seen to be bold impositions; and sin, as well as disease, & death, give everlasting place to the scientific demonstration of Truth in mathematics, and to God, the Perfect Man, Allah.” - Minister Aleek Jahkim Allah
