Yes, Yoshi is Japanese. That particular line about "crackers" wasn't directed at her. Normally, Yoshi seems to make some sense, but on this issue, she's lost her mind. It must be post 911 trauma.
As for whether Japanese, Chinese, Korean, and some other "Asian" peoples benefit to a certain extent from the perverse hierarchy of White Supremacy in the United States, YES, they do. Under the system of White Supremacy, they do enjoy a certain amount of "honorary white" status. This is a fact.
