The Goggles Do Nothing
We minorities ought to get to have fun too instead of being Eagle Scouts all the time.
I agree with you on this matter in every way but with Booster Gold, who (as I see his origin, which is obviously mutable across mediums and eras) is privilege personified. I feel like, correctly handled, BG could be an excellent mirror for the throngs of white dudes that see themselves as (inevitably already white) superheroes like Flash, Arrow, or Superman. Something that says "you're closer to Booster Gold than the billionaire playboy that is also a super detective and amazing athlete" would be severely blunted by having him be anything but "another white superhero". Even when Ollie or Barry are having bad days, they're hailed as the literal center of their universes, and it would be great to have a white guy that reminds other white guys that that is not the case for actual reality.
And, yes, I am arguing that because of white privilege, only white characters should experience white privilege. It's an ouroboros !
All that said, you and I may simply be approaching Booster Gold from two wildly different perspectives. If Booster Gold is going to be a fun dude that is just kind of a fuckup, then, to be clear, I think it would be great for him to be whatever (and we need more non-white cis superheroes). But even at his yuk-yukiest, I've always seen BG ultimately presented as a cautionary tale when he stands next to "real" superheroes, which is what I would expect to be more emphasized on the dramatic side of the CW-verse.
Anyway, I'd just be happy to see a recognizable Booster Gold (similar origin, and not some weird CW approximation of a time traveler superhero that more easily fits the continuity) at all, so there's that, too...
