comics = trash?

I've already loved comic books, even though I did not grow up in the Disney dream. But comic books were the first "art form" I knew. They offered me opportunities of imagination when there was no art environment for me.

The first comics I ever read was Do Ra A Mon, and I was 5: 

and of course it did not contain any sex, drugs or R&R elements.

The second one was Sailor Moon:

and it started to have violence involved.

I moved to Detective Conan which has a lot of death:

and right now I'm following Bleach and One Piece:

But none of these comic books I've read are similar to American comic books. I guess it is the eastern/western difference. Western comics are short and involved with ideas of self-expression (pornography in a way), and jokes I sometimes can't get. Especially for those underground graphics, they reflect the hidden history of culture, they contain political messages, and they always confused me. But I still appreciate them, as art.

I'm not sure about other people, but if they consider comics "trash", does that mean one day, art will become trash too?

p.s. I just realized that all the Asian comics I've read are Japanese. wow.
