Hello @TheOriginalMagratGarlik - special though to the OTBT thread and our bats 
I come late to the battle - however, I would agree with not ignoring the extremes; they do exists, because shitty fuckwit departments do exist.
I can't say I have quite the same set-up as magrat, but not far - until ~1.5 years ago, I worked til 2am and was back in for 9am, and was still blacklisted during the last REF as not producing enough 4* papers - after all, we all love a bit of public humiliation at college meetings.
Now, with the advantage of being a bit senior, and clearly not promotable to the next rung of the ladder (short of a few millions) I have mellowed a lot. BUT, I still work with fuckwits - the types who scream during academic meetings when something was not done because you were off sick
. And why do I not tell HR? Because HR does not give a crap what-so-ever.
I don't think academia is a sane job - at least where I operate. But my discipline is full of crazies, and my unit is not known to be the worst...
I am very sorry to hear, in the above, that so many have had such horrible experiences. It does not denies the fact that some of you/us have a normal happy employment in academic, but we still need to acknowledge that the environment is still often sour and toxic.
Would I want my daughter to start a PhD to become an academic? HELL NO!!
