You're assuming that a major chewing-out of one person who's stepped WAY over the line is going to equate to your getting pissed on if you pose a reasonable, private question to the mod.
Threats are designed to cause fear, it's unreasonable to make open ban-threats directed at a thread at large and then expect people to accurately interpret who they were meant for. Personally, in those instances, I assume that everyone is included in said threat/warning regardless of having violated rules or not. I'm not a mind reader, it's not up to me to assume or figure out who was being chastised and who wasn't. So I find it only reasonable for me to make that assumption.
Plus, and I repeat, you still don't have anywhere nearly all the information. I've SEEN massive chewings-out. They're a sort of compliment - they mean that the person getting chewed out at least seems to have the POSSIBILITY of straightening up and flying right, becoming a contributing member of the forum. WJM is a perfect example. He was (sorry, WJM, but I think you'll agree) pretty damn dickish. He got a thorough chewing-out and now he's a member in fine standing here - because, as he said, he didn't just negligently get booted but was actually ADDRESSED, actually given more than just "You screwed up" to show him how and how BADLY he had stepped over the line.
This goes hand in hand with how you don't "want to read constant exasperated 'I'm so sick of you people' posts by admins" honestly misses the point. Yeah, the mods could just boot people. Do you really think they'll learn? Especially when they're repeat offenders who have more than once entirely missed the point about HOW they're offensive? If a punishment is to have any effectiveness, it must be strong enough to catch and HOLD the attention of the person receiving it. They have to know in absolutely NO uncertain terms WHAT they did, WHY it's wrong and WHY it's not fit for polite society. And when there's a whole freakin' flood of people doing that, are you honestly surprised that there are "I'm so sick of you people" mod posts?
And finally, aren't you exaggerating a lot with the "constant" description? Happened a handful of times, and anyone who honestly claims that those times were quiet and peaceful and NOT exasperating as hell needs to see a surgeon to fix that rectocranial inversion.
I can't really comment on the example of WJM since I didn't witness the events in question. However, whether or not I have all the information is irrelevant if I'm being subjected to the end result. Keep in mind, I'm not passing a judgment which requires me to have the full information, I'm commenting on things which admins/mods have chosen to expose me to by openly posting it.
Even if member_01 went off calling me every name under the sun resulting in me reporting the post, I still would have no desire to witness a mod/admin beat them down. And if an open post was required by said mod/admin, I would prefer it to be assertive yet still mature and respectful. I don't believe in calling in a bigger bully to beat up the smaller bully; if they're both bullies, they're both wrong.
As to my use of the term "constant", I believe it was fitting in regards to posting proportions. For example: if admin/mod_01 makes 10 administrative posts in a week and 9 of those are offensive, I'd call that constant. And in my opinion, this has been the case in some instances, maybe not throughout the course of a week, but the example is still valid.
