It really does sound suspect, doesn't it? Like, the impression I'm getting is that the interviewer wanted to downplay the actual controversy NaruHina caused, making it sound like it was only in the States that it was a major point of contention and the rest of the world accepted it without question.
As much as it is true the the primary base of support for nH is the states. This is also the only place that had petitions as a reaction to the ending both trying to force-ably change the ending and ban it from the country. Granted both were made by a nH fan with the intention of trolling. So, they have to pretend that this is the only place that nH wasn't completely accepted. When he we know that is almost the opposite. It wasn't liked almost anywhere.
What I don't get is. If NH was so popular in the US, then why was all the advertisement still NS? Were the marketing people not doing their jobs? It also is a good example that the ending was changed from NS to NH at the end because of how much NS was marketed together.
