Apparently "slope" is a derogatory word for any Asian? So that's another few hundred million people to be offended.
The term "slope" was coined by American military, during the Vietnam war, for the Vietnamese, and then expanded to all mongaloid people. The woman making the complaint isn't "mongoloid", she is from the Indian Sub-Continent, and out of the three main classifications; Mongoloid, Negroid, and Caucasian, she would, unfortunately, fall into the Caucasian group of peoples. So, basically SHE isn't being insuled, even if Clarkson was calling the guy on the bridge a "slope". But hey
