Yeah, but that particular page was more a single symptom of the tendency to treat him like that, with some equivalent of the phrase "But at least I'm not like Guy" showing up fairly often, marking him as the black sheep of the Justice League.
Sure, he's a jerk, an ass, a poltroon, a pig. But if one were going to pick a black sheep out of the Justice League, or even Earth's Green Lanterns, there's always, oh, I don't know... HAL?!?!?!
The guy couldn't hold down a job, he constantly waffled around with his love life (Star Sapphire complications aside), he's got a whole meme built around him about punching allies in the face, and really he's kind of a dick himself... he just kind of comes off as the sort of dick who knows to give a charming smile and a wink when he's being a dick, so he comes off as "cheeky" instead.
I mean, wasn't Guy actually Hal's parole officer when they met? Talk about black sheep...
But anyway. I just think it's kind of unfair that Guy gets relegated to the role of scratching post purely based on his personality flaws. Kinda disliking him, I get, I mean I'm not a fan of the character myself... I just think it comes off as a flaw in the other characters' personalities when they don't give him the respect he's earned. If nothing else, they should treat him better because being snarky about him makes them look worse.
