I think they fear a white girl fan base. I'm paying close attention to this shit. It's beginning to feel orchestrated. The Flash young 20 something awkward but loveable. You get Kid Flash who is an awesome addition who has a girlfriend we never see and the real life actor is gay. Arrow who is another 20 something who takes charge and women swoon over. Here comes Diggle who is his physical equal who plays his incredible dutiful sidekick who runs behind boss Oliver at all costs. Everyone has a mind of their own even go off on their own but good old digg knows his place. Hell the character has killed only one person after seasons and they made sure it wasn't a white criminal it had to be his own brother. Then we Legends where the only black guy hero gets his power by joining up with a white guy. No agency of his own, his power isn't even his without the assist of an older smarter white man. And to top it off he is literally the only main character without any romantic interactions save for the fire guy who has no ambition outside of burning shit up. Yet the two female characters on the show always seemed to find love with some white guy. Lastly we have Supergirl where the main character did like a black guy but they barely shared a kiss after an entire season. They destroyed that love story absolutely no work in that part of the writing. We also get a rarity of having another black guy who is also the Martian Man Hunter who is considered the most powerful being on earth according to Superman yet for some reason Supergirl constantly calls the shots and he is also another one who gets no love story. Her gay sister gets a love story even the little tech guy gets a reoccurring one but the black men nada.
