The funny thing is the accusations of Frederic Wertham in "The Seduction of the Innocents" in the 1950's that comic books led to juvenile delinquency (and homosexuality Batman has a young boy who lives with him, the dress in tights etc blah blah) led to the Senate Subcommittee that led to the Comics Code Authority, that was a little logo on comic books that said "CCA" in a logo that looked sort of like a postage stamp. I don't think any of the comic book companies abide by it anymore. I heard Marvel (Spiderman, Hulk etc) dropped it, I'm not sure about DC (Superman, Batman etc).

This logo used to a bit of assurance to parents that they could let young children read the comic without running across material that parents would find objectionable.
Although children may be more sophisticated about sexuality (for better or worse), I still don't think most parents would want their elementary and junior high school age children reading comic books that portrayed homosexual relationships between teen age boys as acceptable (and I guess fashionable by having the hero involved in one). I guess comic books are as anxious to appear "cool" and "PC" as the rest of the media now.
