See, this actually gets at something that always kind of bothered me about the Giffen Bwa-Ha-Ha league. Booster's right--put-downs and insults do hurt, and while I'm as big a fan of banter as anyone, being insensitive to someone's feelings is simply not the kind of thing I want to see my heroes doing. Giffen et al were extremely talented at writing sharp, witty dialogue, but in the context of the Justice League, I always felt that this distracted from the fact that these characters were human beings, first--and that maybe being mean to each other all the damn time wasn't actually the best way to organize a team whose primary responsibility was saving peoples' lives from serious threats.
There's really only two ways you can read the Bwa-Ha-Ha League: one, that they're just cartoon characters, who bounce around yelling insults at one another and facing comically-overblown crises, and nothing they do or say really matters. Or two, that they're real people, with histories and personalities, and they're just constantly at one anothers' throats, always cutting one another down and undermining their respect for one another. And if that second one is the case--as Booster is suggesting here--then that kind of behavior has serious consequences.
I love the character of Blue Beetle, particularly because he's very much a normal person who is doing the best he can, and he's constantly getting nothing but crap from everyone else. To be fair, he made plenty of bad decisions and may have grossly overestimated his own abilities any number of times, but he's generally portrayed as being treated like an incompetent fool by his colleagues, and that had to be painful. Frankly, I'm with Booster on this one; all those people who are looking so sad at Ted's funeral might have thought about treating him with more respect while he was still alive, instead of waiting until too late and then saying "Whoops, my bad."
Obviously I'm getting a bit ranty because this is sparking some deeply personal feelings for me, but I think it's a good bit of writing nonetheless and I like seeing it made canon. Go, Booster.
