So out of all the options, even just limited to the main 7 of the Justice League, they decided to go with the one known for being from an island of only women. A point that's been so important lately that even Steve Trevor had his previous "first man on the island" status retconned when Diana's twin brother Jason was written in to the comics.

That's what they went with.

Instead of the shape-shifting Martians.

Or alien Thanagarians.

Or multiracial Green Lantern Corps, which they've already added 'Teen Lantern' to, a young black girl written in by Bendis [stop me if you've heard this one before /cough Riri, Noami, etc], who gained the powers of a Green Lantern ring by... stealing it and hacking into it because teen genius y'all [again /cough Riri because Bendis has literally zero fucking creativity and keeps self inserting his daughters into comics].

Or something stupid about the Speedforce since that's been fucked up several times in the last few years anyway.

Batman has already been replaced by a rich black man now so can't do that.

Superman has been replaced by his own son who was aged up so much Jon has zero fucking personality except he's... now gay, so can't do that.

No, they went with the "island of all women".

Well, this is the bed wokesters made, they can share it with their new "girlfriends".
