When someone picks up a copy of Supergirl they make an active choice.
They look at the comics shelf and see a Batman comic with some laughing bdsm joker with spikes and think: “No, I want to read something more wholesome.”
So they pick up a comic about someone who carries the mantra of hope, help and compassion for all. Someone who sits down and talks with villains and reforms them. Someone who stands by the bullied. Someone who provides comfort for those in need.
Then every once in a while somebody at DC gets a stroke and forgets that. And gives us this bs.
Who was this comic made for?
If Batman wants a perverted version of good to fight, keep that crap over in his comics. He has like a billion comics coming out each week. Supergirl comes out once a month, and appears almost nowhere else.
If you want to involve her in the year of villains - cool. Use her as she was meant. Be the good. Be the change. Be the hope. Don’t do this.
