The two questions about feeling angry are nonsense.
It is not posible to answer other to question 5.
This an important issue not only for people who either are angry at the japanese - mainly japanese. Or those who claim that Japan does not need to feel ashamed - a small minority of right wing japanese nationalsts.
If people are to use their time dooing this questionaire, it should at least be meaningfull questions. It should either be remade or cancelled.
