Funnily enough, Blue Starman isn't bisexual. Among his own kind, he's only attracted to the female of the species. He's got a boyfriend here (well, he had, until he got fridged in order to motivate Blue Starman to find JUSTICEJUSTICE) because humans are so alien it makes no difference, or some ass-covering noise like that.
Anyway, point remains. This is a story about a team of entirely white folks (Blue Starman may be blue, but he codes white, and Congorilla is a gorilla, but he used to be white), which opened by killing off a bunch of D-list (read: won't be rezzed) minority characters in order to motivate said white folks, and has now killed off a couple more D-listers in order to show how badass his villain is, including yet another of the DCU's vanishingly small pool of gay characters. It's like he thinks he's writing a Big Linewide Crossover or something. It's more than a little annoying.
