Mr. Smith, I am a Native Hawaiian and I immediately felt offended by your use of "luau feet" in your response to another Native Hawaiian.  I do not know your intent, simply, this is how I perceived your use of "luau feet."  You have yet to explain how your use of the term was not directed at the OP's race/culture.  To me, it currently stands as a racist comment.    

Your analogy has no relevance here.  It would appear as though you're now trying to deflect your bigoted actions by drawing out some kind of convoluted response.  You told a Native Hawaiian that he was "sticking [his] luau feet" in his mouth.  You could have simply said he was "sticking his foot in his mouth," but you chose to use a racial/cultural identifier.  Yes, you were showing your intolerance.
