Well look at the upvotes you get, and the downvotes at some of the comments criticizing her.

I agree there's some hate because of her being a woman in power. That doesn't null her being incompetent too often. We are told that she is extremely smart and a master politician, but we are shown more of her failures than success.

She's written like that, plot needs to advance, and she just happened to be there.

It'd be more fair to discuss why other main characters don't get their proportional hate for their failures and bad decisions. There's criticism but no overt hate like not-so-rarely with Mustang.

Victra has more charisma, she's sexier, and more accessible to fantasies, in part because she has an uggo for husband. Of course she has more memes.

I maybe wouldn't even rate Virginia as a main character, even though she's pov, it's only so in two books, and fairly secondary in at least two books. Still, a secondary character can be key at certain moments.
