德国和犹太人and日本的南京大屠杀 are two major events in WWII.
I got very angry when Japanese denied 南京大屠杀. I once fiercely debated with a Japanese and angrily condemned him. He, somehow, reported it to my boss, an American. My boss talked to me gently and I replied that he should ignore it. Then, my boss smiled at me and said ``good day". After that, my boss has treated me as before.
Now some Chinese are talking about 德国和犹太人. If Jews deny 日本的南京大屠杀, what will you say?
