Dude, relax, it's a taste thing. Dennis doesn't like anime, the style (or at least the stereotype, since all anime doesn't look the same). He wasn't slamming the whole of Japanese culture, or even anime itself. Just said it wasn't his thing.
Least I assume that's what you were talking about since it's kinda hard to tell. And if I got your position wrong, Dennis, please correct me.
Me, I love anime, but the idea that someone saying that it's not his thing would inspire a post like the above...
...is kinda funny.
