1) The Japanese are pets. They're docile and submissive and their women are masturbation aid, (and their women are physically indistinguishable from other East Asian women). They're loved but not respected. Historically speaking, the Japanese were the first East Asians to widely buttfuck the Western Europeans in the setting of modern warfare. The Mongols performed a similar function but it was limited to Eastern Europeans, (and we can probably thank the Mongols for the AMWF/WMAF ratios that continue to persist in presentday Eastern Europe.) But what the Japanese were, the mechanized Yellow Peril, and what the Japanese are now, a selfcucking American vassal, only accentuates the degree to which they were defeated by America, hence, "Killing the Rising Sun". Similarly, what America now is and what it will be, together with this unconscious recognition of the nature of Japanese defeat, breeds a great deal of white male anxiety as regards the Chinese.
As for yellow fever, it doesn't seem to exist in a physical sense, (ex. Amy Chua and Priscilla Chan mog their husbands). It's more psychological, more to do with the slavishness of whiteworshipping AFs. Every man wants to be accepted for who he is and AFs give the meekest of white men the experience normally accorded to Chad/Chang/Tyrone. Hypergamy is getting bad, and being accepted is a real need that men have, so white men can't be blamed.
