which attitudes?
that japan received no cheering?
I'm sure if your grandparents were nearly killed by the invasion of another country [and at the same time something close to 11 million were reported killed, including the massacre at Nanjing], hatred would be fairly justified.
at the same time, do you also criticize the fact that north korea and south korea requested not to march one after another? that Isreal is still fighting with Palestine? that some members of the Jewish community are still very anti-Germany?
that every nation held the Chinese flag? it happens at every olympics, participants hold the host's flag as well as their own. at the end of the day, they could've chosen not to hold the flag [i remember seeing a few middle-eastern and african nations who didn't hold the chinese flag]
that Taipei received glares? hell, at least their cheering was a lot more than Japan.
if Western Australia decided that they should declare independence from Aust. Govt because they can, do you think it will be granted?
the main reason is that during the civil war/japan invasion, the Republican party chose to ignore the killings in Northern China, and turned its attention to the Communist party, who must be irradicated in the principles of "宁肯错杀一千,决不放掉一个" (rather kill 1000 innocent people than to let one communist escape). are you telling me that hatred in this case is not justified?
