Green Lantern fans have a reputation for rabidity. The infamous Hal Jordan fans vs. Kyle Rayner fans feud raged for well over a decade. The writer of the issues where Kyle replaced Hal recieved death threats and still gets regularly trashed by the most extreme readers. The writer who wrote Rebirth gets similarly trashed by Kyle fans now. Before Hal came back, we had little Kyle fan vs. John Stewart fan fights on message boards and even now, with three series and five major Lanterns there's still little skirmishes on the internet.

They are like us because each one, no matter the species or gender, is a geek, a dweeb, or a nerd.

Hal's test pilot on fight jets, he has no trouble getting an overnight dance partner when his girlfriend turns into a naughty supervillainess, he gets to just punch out whoever disagrees with him without every getting assault charges or a broken wrist. Hal was never a dweeb, right?
Well, here's Hal reminiscing about his childhood:
