Off topic, I know.....
Its all due to different cultures. Like here in America, parents who have baths with their children is considered wrong, or cousins marrying one another, any family member, is against the law.
While over in Japan, its legal to marry within ones family, and have a bath with parents. Also with the anime and its cuss words for the Japanese, vary with different districs in Japan. Lets say your in Tokyo, and you call someone a "baka". It means dumb or idiot. While over, lets just say, Okinawa, "Baka" would me A$$. This one word, can mean different things in differnt area's of Japan.
Besides, I've seen American cartoons that sickened me "Cow and Chicken". That shock me they are even able to be shown on children's network. So seeing a bloodyer Tsubasa would rule.
