Okay, I have been asked this a lot. I have only read the first issue of Teen Titans so I don't know Bunker yet, but he seems very polarizing. I've heard from lgbtq folks who REALLY don't like him, but then I've also read really positive stuff from lgbtq folks about him. I wish I had a better answer, but I'm not really caught up.
I'm not dodging it, I'm just behind on some of the 52 books. I still haven't read the Catwoman and Red Hood books people were freaking about!
I will say I just looked at some scans, and I like how he appears to be a happy, positive character. That's actually quite nice to see.
