Western comics are for nerds coz it's all like: "Hey, I wonder how my fave fictional, muscly man in spandex is gonna save the world this time?? I hope he says his catch phrase: Jumping Jillickers Gimp Boy! I'm not wearing enough spandex!"
But with manga it's mostly like, decent fighting scenes, violence and clever plots.
So ya, manga's for nerds, but comics are for gay nerds.
