Annoying Unbelievers

[Lalaith]

Ok, we've done annoying experts and amateurs, what about those who mock what they do not understand?

To illustrate what I mean, I had an utterly idiotic argument with Mr Lalaith the other day about Numenoreans. (He's seen the films but never got past the Hobbit, book-wise) He gathered from a conversation I was having with someone else that they had a much longer lifespan than ordinary men.
The conversation went something like this:
"So Aragorn is not human then?"
"Yes, he is human, but his race just lives longer."
"I'm sorry, if they live longer than men, they can't be men."
"Look, Tolkien created them, if he says Numenoreans are men then that's what they are."
"But it still doesn't make sense."
And so it went on. Sigh. Has anyone else suffered in this way?
