It's not a cultural thing, no. I was raised (possibly improperly) to respect authority without much question. If a moderator is abusive, I do my best to avoid that moderator completely, sometimes by avoiding the venue they moderate altogether.
To put that into context, if I found Morwen to be treating me unfairly or abusively, I would stop using Backstage. Morwen can attest to my habit of leaving channels that I have a problem with ingame. I'd do the same here.
This is how I handle authority that's oppressing me, by hiding under the couch. I'm not saying it's the right way to do things, but it's something that I've done for many years, and so I find it strange and aberrant that people so boldly and loudly complain and even attack Morwen for the way he moderates. I understand why, but I just cannot relate to it, because that isn't the way my mind works.
