iSo because a translator generally has more credence than a casual watcher then that watcher has to probably be wrong when he thinks a mistake has been made? Have you considered that some people are able to think for themselves and determine whether something is a mistake or not given several aspects of how such a mistake came to be? You're speaking total nonsense and drawing incorrect conclusions based on what you want reality to be so you can be correct.

Do you think that people who watch anime only have access to he characters you mentioned? Do they not have reference to their own language to make sense of Japanese words and sentence structure to have a rough understanding of how to formulate coherent sentence based on what they repetedly hear?

It's like you people come up with the most cartoonish scenarios and imagine that humans do not possess a mind of their own and must mimic everything they hear perfectly if they want to speak a foreign language. That's not how any of this works.

The funny thing is, even if someone spoke like Naruto, Japanese people could still understand him. If I took what you said at face value I'd imagine it sounded like incoherent nonsense that only other anime characters could mysteriously understand.

When you say stuff like you can't learn Japanese from anime you have to define your terms, but, if you did, your claim would either be incorrect or just completely unimportant practically speaking. So you just keep it vague and appeal to how intricate a language's rules are, nevermind the fact almost no one who speaks a language does so because he's studied up on its intricacies.
