On this visit, he told me that ALL sci-fi is stupid because, as stated above, it's too "unrealistic".
He also went on to say that the only people who like sci-fi are "mentally deficient".
After insulting my intelligence, the rest of the visit was pretty awkward.
I've heard that same kind of statement from two people at least, one of them was my Art teacher. And it always blew my mind how much sense it didn't make. I'd hear that sentence being uttered and I'd stare, thinking "What?.... Wait, what?.......No, wait, what??" I never know what to retort. But maybe that's okay, otherwise I should memorize a site like this: http://www.moviecliches.com/
and explode it in the offender's face in an endless logorrhea.
