To quote one of dozens of similar comments:
"Why is Japan doing this??"
JAPAN is not doing this. A GUY is doing this. Granted this guy is a product of Japanese culture. But so are 127 million other Japanese people, each of whom is a person with his or her own personality, none of which are precisely identical despite the stereotype.
"JAPAN" is not some monolithic hive-mind. There's one guy in Miyazaki Prefecture (a tiny, mostly rural "state" tucked away in the far south of Japan...the size and population of a couple of American counties) who thinks this way. There are probably a few million others who have similar ridiculous opinions, but most Japanese people would find his views as appalling as most of us do.
And how many millions of Americans think that homosexuality is caused by dominant women? How many Canadians? Dave Sim, the writer of Cerberus, one of the greatest comic books ever, thinks so. Most North Americans who've read his wacky views rightfully think he's a nutcase. Do they say, "Why is Canada doing this??" No. They think, "Why did such a great comic creator turn into such a homophobic, misogynistic creep?"
Why is a Canadian or an American opinion an individual's opinion, but a minor Japanese functionary's opinion is suddenly JAPAN's opinion?
And for the several people who wrote variations on "This is why I hate Japan": Stop being idiots. I could understand such a sentiment if you were, say, Japanese and complaining about your own culture, or if you were Chinese or Korean and your country had been invaded and terribly harmed by Japan, or if you were an 80-year-old Pacific War vet. But even those people should get the hell over it. Americans should remember that Japan is one of America's closest and most loyal allies. It is far from a perfect country, and it has crimes to answer for in its history...but name me a country that is perfect. Name me a country that is free from an ugly past.
