The genocide Japan committed against China, in which they murdered millions of people, is every bit as horrible as the atrocities the Nazis committed. Further, the Japanese committed genocide against many other nations in Asia as well during that era. Unit 731 did things to people that were very comparable to the worst atrocities of the Nazi regime.
How are death camps, the specific targeting of civilians, medical experimentation on detainees, burying prisoners alive and even cannibalism covered under "war of conquest". When does it become genocide? How is it any different (if not worse for its unparalleled scale) than what the Nazis did?
They didn't just target Chinese civilians, they targeted the civilians of every nation they invaded. This includes the British civilians in Singapore and Hong Kong who were sent to ghettos and labour camps, few of who survived. And this was the "preferential" treatment the Brits got. The Chinese and other Asians got far, far worse.
While there are a few groups that call themselves the KKK, as an actual national organization they were gutted by the FBI decades ago. Whenever any self-styled "KKK" group gets large enough, the FBI infiltrates and guts them as well.
It is hard to weed out a general mindset or philosophy entirely, but tearing down organizations is surprisingly easy.
Mind you, there's a downside to that. An FBI that can infiltrate and dismantle the KKK at will can do the same to any legitimate movement for change, like Occupy, etc.

Regardless of what you were thinking, you said it and i could not have possibly known that you were not actually thinking that, precisely because i have encountered a great and numerous amount of people in my years who do carry that belief. I was not joking when i told you that you were literally indistinguishable from both a very motivated troll and a complete prejudiced ignorant, with no feasible way of determining which it was. If you don't think something, don't say it.
