It's very sad, I grew up obsessed with Buffy, especially as a teenager. I know that there has been speculation for years now that CC's Angel character was killed off in spite because the actress got pregnant, and his ex wife published a statement about his bad behaviour towards her.
Back when Buffy was still on air, I used to read a lot of James Marsters interviews (blame teenage hormones) who I remember always used to tell weird Joss Whedon anecdotes, but laughing them off as funny. Things like, "and then Joss pushed me into the wall and said ... Hahaha!", and I'm sure most readers would have thought "WTF?". I think people just felt that figures like Joss Whedon were untouchable at the time and that they just had to put up with it.
Some might say that this is a case of judging someone in the past by modern standards, but I think he stood out as behaving like a dick 20 years ago.
