Gaiman has vocalised support for feminist ideas while at the same time sexually abused women. That's pretty hypocritical and taints his fictional characters that display similar worldviews that he espouses in public.
He's a sexual predator, buying his books is literally supporting him financially.
I never saw him as a hero, but I believed he supported woman based on his words and the persona he falsely projected. But the opposite is true. He actively hurts vulnerable women.
Are you familiar with his work? It seems not, based on your replies. Trust me as a fan, Gaiman's real-world actions are directly at odds with his common fictional themes and characters. A lot of his fiction is tainted now.
