Could you imagine the backlash if the first black Captain America melted down his shield for cash?
I think there were pacing issues that made the race stuff not play perfectly. Like RIGHT AFTER the old, (deservedly) self righteous black man gives his speech THEN the cops come with the "Is he bothering you?" shyt to Falcon? That needs to be spread out or done a less cliche way.
In fact,
the whole Isaiah Bradley stuff needed to be a lot more "show don't tell". I would've loved some flashbacks: Him and the Winter Soldier fighting, him seeing the re-appearance of Captain America, him hearing about the Winter Soldier killing the King of Wakanda, Bucky having Isaiah on his list and trying to reconnect but failing, and finally Bucky misguidedly bringing "his black friend" (Falcon) to Isaiah's door step.
I can imagine the scene hitting way harder after that and Isaiah thinking "Is this your peace offering? Steve's black side kick?"
