Crisis is the perfect time to set some corrections, but I doubt they will.
I tend to agree that one should place too much hope on any major general series / changes where the A-list characters are concerned. In other words, the fantastic, meaningful drama that was born of (for one thing) the idea of sacrifice as seen in the original COIE comics will never find its way into the Arrowverse series. It would be a brave, jaw-dropping move if they took the various series in that direction.
This is an interesting take. I can't and won't comment on whether they wrote a black character effectively. But I am certainly in the group that hates seeing casting based solely on race just so a bunch of people can pat themselves on the back about how woke they are, and then get fake outraged when they are called out on their blatant pandering.
One could comfortably say that a large number of Arrowverse viewers do count themselves as very liberal/progressive, yet some of those same people resented the idea of Brooks being cast as Olsen, or never found it grating that of all of the main characters on a show where exploration/expression of identity is of the greatest priority, that James---the one black male--had his identity/development feet cut from under him, left to be little more than tokenized wallpaper instead of a character that represented his real world counterparts with a unique story to tell (one that is experienced from one generation to the next), yet that was of no concern to the showrunners. .
Brooks basically played what should have been Ron Troupe on this show with a James Olsen name.
Interesting.
