Adams has become a controversial figure in recent years. Regardless of what you think of him, as someone who has worked in Corporate America for over a decade, there really isn't anything quite like Dilbert to describe the sort of white collar insanity I've had to learn to take in stride. My first workplace as a junior developer was straight out of Dilbert and Office Space. I have a gigantic collection of digitized Dilbert strips that best describe office situations I've run into in real life – many of them including the pointy haired boss.
He's expressed a lot of what I would consider... stupid opinions these days, but I would be sad to learn he's no longer with us.
Adams, himself? Not so much. I think he tends to have a rather nasty outlook on humanity, and I had a hard time reconciling it.
I do know that he was/is pretty much about as far away from Diamond Joe* as you can get. Interesting that they seem to be fighting the same battle.
This has always seemed like the flimsiest argument. It costs nothing for JK Rowling to tweet. On the flipside, the joy and wonder her books have produced for the world dwarf what else she has wrought and in the end her life will be a net-positive, more so than your vegan co-worker. Doesn't make her a good person, just a net-positive.
