Bigoted: "having or revealing an obstinate belief in the superiority of one's own opinions and a prejudiced intolerance of the opinions of others."
For example, the author's response to people who took offense to certain sexual/LGBT content of the comics was to nastily opine that he wished he'd done it sooner so those readers would have gone away years ago. I can imagine the way a classy guy like Jim Butcher would handle a similar situation (probably something like, "Hey, that's the story I'm telling--I'm sorry you didn't enjoy it") but Rich Burlew had to make it a way to mock someone for disagreeing with him. That's bigotry, and I'm not okay with it.
