As I said, didn't know it was that bad.
On the other hand it's somehow understandable, that some people get angry if they only hear the shit from Debs Craig told her.
Again, it doesn't matter how bad it is, if it was one or one hundred, the point I'm trying to emphasize here is that if you do anything, no matter if it is malignant or benign, you made the choice, no one coerced you into it (except in cases where coercion has happened of course, I'm hoping I don't have to explain why what is going on here isn't coercion).
Write the nasty emails if you want, just don't say that Craig is responsible for those emails. It isn't Craig's fault that people wrote nasty emails any more than it is the boss's fault that the man in my previous analogy went home to beat his wife. Just because someone is an asshole to you does not give you carte blanche to act like an asshole yourself.
Should people be mad at Craig? Probably, he hasn't been transparent with anything, pretty much ever. Should we then automatically forgive people (whether few or many) who sent these threats because "it's human nature"? I say no. I also reject that it is "human nature". Human nature to be angry, perhaps, but humans have successfully not blown themselves up over petty squabbles on several occasions, so I'm quite certain it is within our ability to not send nasty emails no matter how angry we might be.
