It's ok, even healthy, to be critical of something you like, especially when talking about entertainment media. I mean ********, I won't touch the New 52 with a ten-foot pole because the blatant amount of sexism and homophobia in certain titles baffles me. (It's not "progressive" to make Alan Scott gay if you're going to kill off his boyfriend in the first issue, DC.) Yes, the comic industry is mostly run by cis straight white dudes, but it's not necessarily the consumers they cater to--and they need to adapt. I'd say the same things about television and movies, only comics have and even broader audience (in my opinion) and have been subtly dealing with social justice issues since forever, so why take two steps back by, say, messing up Starfire's character and essentially turning her into nothing but a male fantasy?
Marvel, in that sense, is better. They have actual queer couples, more racially diverse characters, more strong female characters...it's not wrong to look for those in comics. It's not wrong, as a minority, to want to be represented in your favorite media, and to want that media to reflect society. But it's also not wrong to enjoy comics that are, for lack of a better word, "problematic". I can have issues with something and still like it for the character, or the story, or the art--as long as I can honestly acknowledge that it's not perfect and that some issues need to be addressed.
So yes--yes, I like comic books for the story they tell, and the art, and the characters. The only storylines I'm 100% invested into are Marvel's X-Factor, Young Avengers, Runaways, Guardians of the Galaxy, and everything kid!Loki. The rest I buy are just titles of characters/teams I love, like Deadpool or the Avengers. Then there's Trek, Who, Firefly, Supernatural and Silent Hill comic books I collect, but that's mostly because they're safe bets since I love the source material.
