I don’t mind at all that DC is trying to make a quick buck, which is exactly what this is, but are the so artistically bankrupt that they can’t just create a new character? Why not give them a proper back story and really delve into what it means to be gay in their universe? Superman and Robin have shown no inclination towards homosexuality until DC decided to shoehorn this in. They will get some publicity and sell a few more comic books for a few months, but this just seems to be in poor taste.
It’s really not that uncommon for someone to take a while to realize they’re gay or bi, and until then date the opposite gender because they think it’s what they’re “supposed” to do. Jon’s only previous relationship was with a telepath who has admitted to having a bad habit of psionically influencing others unconsciously. Who can say whether Jon’s feelings there were really his own, or whether he was only reflecting her feelings for him? Really, this is a guy who spent most of his formative teenage years trapped in a volcano. How is he supposed to know how his own sexuality works? He’s never had the opportunity to explore those feelings before this.
