This story is no surprise to anyone who has followed Joss Whedon's rants over the last few years. He is unhinged and his Trump Derangement Syndrome is just a symptom of his increasingly unstable mental health. I like some of his work a lot, but like a lot of artists, he is a complete narcissistic asshat.
And the male feminist stuff? That was just a line of BS he used to lie to his wife and pick up chicks in Hollywood.
