Hmmmmm, my brother says that sort of thing about stuff like anime and webcomics and whatnot. Although he doesn't think it isn't 'manly', he just hates the 'geekiness' of it. I always say to him that it's geeks like us that create all the videogames he likes, that developed computers, CDs that he listens to, and the internet, and even things like TV. If it wasn't for geeks, he'd have pretty much zero entertainment and a very boring life, and so he should show some more respect to the geeks of the world. For this radio guy, I'd probably punch him in the mouth and then break his nose, and then remind him that it was so-called 'geeks' of their time-period who came up with stuff like radio, so it's thanks to geeks that he even has a job.
As far as anime goes, who else agrees here that anime is absolutely no different to American or UK cartoons, except for the art style and the language used? And thus watching anime is exactly the same as watching something like Family Guy or Futurama? Because that's something my brother just cannot get his head around...
