He was the editor of the MAGNETO solo book, too! He loves the X-MEN and knows the characters and their history. I'm so saddened by this news. There is no reason for this other than fallout from Syaf's stupid sh*t in X-MEN GOLD. Ketchum has done a good job as editor, writers and artists all respect him, and the ResurreXion books are doing well. And let's not forget, that he stuck by the X-MEN during the dark year and a half when they were being suppressed, while others abandoned the sinking ship.
Now I understand Brian Bendis' tweets from a couple of days ago, about the strong feelings and passions of the editors at Marvel--I'm just guessing that his colleagues at Marvel have been saddened and upset by this firing, if this is true.
It's not fair to blame Ketchum for something that no one could have caught unless they were already an Indonesian Muslim radical.
Anyway, he advocated for diversity, for fairness in the treatment of these wonderful characters. He loves the X-MEN. I wish him the best.
