Almost anytime something dumb like that happened to Dick fans would just ignore it and so would the writers. Generally other comic characters dumb stuff like that would stick in some way but it's like an unspoken thing where both creators and fans pretend it didn't happen. All the better I say. As for the Starfire stuff she was married and also preganant from another alien dude at the end of New Titans and no one ever brings that up.
Where is the divide in Dick's fandom? Dick's fans are loyal as hell, the only way there would be a divide would be the tumblr style fans. Those who talk about his ass and how he loves cereal and all that crap. This is only very recent thing that happened with the reboot.
