No, he is a comic fan, it's just that his fandom is such a minute, specific part of the medium that he refuses to alter from, even when shown he would enjoy it if he did. Much like how he loves Power Rangers, or at least did, but refused to watch the original Sentai series because they weren't the versions he grew up with.
Even dumber is that even if he loses interest in a series, he refuses to give it up. The Titans was his first comic book so he kept buying issues even after he started hating it, and then kept buying it when it was relaunched as Teen Titans to tie into the show that came out in 2003, which he refused to watch because, as I said with Power Rangers, it wasn't the right version. Some of his most hated moments in comics comes from that series, and yet he bought it all the way to the end, and kept buying the New 52 version despite hating it even more.
Whenever he says 'vote with your wallet' he doesn't think that applies to himself.
