I am no comic book geek, but my understanding is that Batwoman has always been a "lipstick lesbian"--which Ms. Rose certainly is not. Hell, Scarlett Johannsen would be perfect for the role.
My comic geek brother is O.K. with Batwoman being gay--because that is what the character has always been. It's when the SJW idiots change the fundamental nature of an established character that my brother goes berserk.
Here's my suggestion to bend everyone's noodle. Let's have someone do an adaptation of the play Othello where Othello is white and all the other characters are black.
Lots of comic book characters, like Iceman of the X-Men, have been rewritten as gay.
Okay, so who gets the part? Sandra Bernhard? Judy Gold (who I'd never heard of, but she checks both boxes)? How about a real dark horse, Miriam Margolyes from Harry Potter?
Since when is Bat Woman a homosexual?! These homosexual perverts are subverting our culture, our entertainment, our history. So now Batman, Bat Woman, Bond, our Star Wars, and Star Trek character are to be homosexuals?! Tom Clancy’s Jack Ryan next? Captain Kirk? John McClane? Indiana Jones?

What does it mean to be a Jew?
She was so cute that even Adam West appreciated her virtues (yes, that gif is them, and it's real). She even looked good in green - Star Trek, the original series.
I would bet that to the filmmakers/producers, this is basically an excuse for a gay woman character to head up a “hit film”, to further attempt to mainstream that “lifestyle”, with the storyline being completely secondary.
