People know my position on real world dynamics, but I really had a problem with the argument in this scene. Yes, Black people in the U.S. have a difficult time and many do live in fear every day. By that argument, women of any color also live with fears that white men, or men in general, don't. But a Green Lantern has to be able to overcome fear (or be without fear in the older days) in unimaginably horrific situations. The ring chose correctly.
We don't know why "fear" is so important to the Guardians in this version of the DC Universe... Actually if this is HBO... Could Lanterns be set in the same DCU as Titans and Doom Patrol?
1. Each Ring, and the central Power battery has an evil parasite living inside of it, awaiting an opportunity to latch onto the fear of it's user, edging them into a murderous psychopath.
2. Yellow Power Rings are already thing, and fearlessness is making defection impossible if Green Power Ring users can't use Yellow Power Rings.
3. Fear erodes confidence, making the specific ring constructs of fearful ring users brittle or non-possible.
4. Fearless soldiers wade into certain death and die. The Guardians want a high turn over of young fearless idiots, because older lanterns with a bit of gumption start to smell their bullshit. Note how they kept reminding Buffy, that she was really very old for a slayer, even as a teenager.
5. They want liars who can talk down an invasion fleet rather than kill millions. Everyone is afraid.
6. Being literally fearless is a mental disorder, and very rare. Fairly rare? Only crazy people can use a Green Power Ring because "willpower" is nowhere on the never before mentioned on this tv show "Emotional Spectrum" so what it is, the emotion that they are actually using to power their rings is probably "Arrogance".
7. Lost in translation. Most aliens from actually developed worlds know what a Green Lantern is, and know the responsibilities of a Green Lantern, and that the complete job might be something to be afraid of, and they know the exact nature of the extremely simple test that may confront them some day to qualify for lanternhood. As a know nothing hick from the outer reaches, John SR was asked if he was afraid of God picking him up like an ant, and making him float for thirty seconds. When did Star Trek 5 come out? He probably hadn't seen it.
8. The Guardians didn't test John, it was a Manhunter. The test was rigged. They wanted him to fail, where they made John snr shit his PJs, and then recriminate for months, before they came for his son. By the way, grown men sleep naked, unless it's really fucking cold.
9. Implanted memories in John Junior by the Manhunters. None of this shit happened to him or his parents, they are fine or dead, whatever. Well before she fucked him, Zoe stuck her fist inside his brain making John more useful to her needs in a way that the guardians and Hal wouldn't notice. This means that they probably never boned, and she was just inside his brain doing surgery while John was being distracted with real time false memories of getting his rocks off.
10. Implanted memories in John Junior by the Guardians. Do you know how fricking far away the centre of the universe is from Earth? Fuck that. Alien brain Zoom. Hal Jordan student of Sinestro, cannot be trusted to rear a young Lantern in the normal ways of worshiping the Guardians. Even if his teacher was not a traitor, Jordan is still a grumpy dickhead with no respect for his elders. John is not his replacement, John is a trap waiting to be sprung on a pithy old man who is a danger to young minds, intent on polluting the next generation of Green Lanterns with "Human Nature". H.J. (Hal Jordan) is short for hand job.
