"Stewart’s comments made it appear as if Vietnamese-Americans were inhuman and savage."

No, Stewart's comments made it appear as if Vietnamese refugees struggled to adapt in Portland in the 1970s. I don't know how accurate his statements are, but I'm sure he has no reason to just make stuff up out of thin air. Duy Chi Nguyen says it's not true, at least to the degree described by Stewart, but his experiences growing up in San Diego might not mesh with whatever was going on in Portland. 

And if Kitty Piercy finds the edited video offensive and racist, why does she share it on her Facebook wall?
