Well in england the only people i've met who are into this stuff are really into this stuff.
They basically sit in some seedy comic book shop (ours are all generally dank, and always seem to small for there stock (i say this having walked into like 2 ever and walking past only a few more).
I don't think being into comic books would even be considered normal here. The only person i can think of who was into comics was really nerdy and even he didn't have that many comics. I think being into films is the more common thing you see here.
I get the impression (though i'm probably wrong) that me, nonny and sim are more inclined towards gaming and film then comics and manga, thats definitely true of me at least. Although i am pretty open about my one piece love. Although that said my friends think i'm a huge DB fan i think they don't remember one piece as its not really heard of here at all.
