"I Don't Read Comics"

I shouldn't be insulted but I am. This was just said to me, by the same guy who said there's no such thing as global warming. This is also the same guy who thought Da Vinci Code was great and original. Should I have told him that the concept contained within the Da Vinci Code, I first came across in Preacher by Garth Ennis, which was many years prior to the Da Vinci Code, so when people all around me were all agog with the blasphemous concept, all I could manage was Ho-hum?

[Added] I just remembered that this guy keeps quoting from his favorite movie: The Crow, starring Brandon Lee. Do I have the heart to tell him that it was based on a comic book, that had a small cult following (the Teenage Mutant Ninja Turtles had a much larger following and actually TMNT started off being a satire before becoming what it mocked)? Half the stuff popular culture thinks is cool, had its dang origin in comic books.
