I couldn't care less about the lazy comment. It's the "slanted eyes" I have an issue with. And no, it's not "just a description". Calling an African-American the N-word could be "just a description" too, as the root of the word is from the "Latin/Spanish/Italian/whatever Romance language it was" for "black", yet the connotations behind that word go much deeper. As to references to slant eyes.
So umm... how is calling someone the N-word a description? That's just a slur and describes nothing other than implying they African-American (which I hate saying because I honestly see nothing wrong with saying black). Asians do generally have slanted eyes on the other hand, thus being an actual description. That, and I have never heard slanted eyes as some bad connotation with chinese. A connotation, sure, but I have never heard "slanted eyes" used as something bad.
