Hey, IAMBIC, welcome to the SDMB. Reading your first post in the other thread, I did see that you were just trying an experiment and didn’t mean to sound obnoxious. The responses seemed overly defensive at first, and I think you – perhaps understandably – were confused, frustrated and affronted when met with their comments.
If you don’t mind my saying so, that’s where the problem began. Rather than explain your rationale/motives more clearly, you yourself got a bit defensive and kinda … oh, lofty, I guess. Things developed from there. But you didn’t come across as a smug jerk in any way to me, though. (And AFAIC, the Czarcasm smackdown came totally out of left field.)
This pattern happens a lot with guests – especially those whose first posts can, in any way, be taken or misconstrued as superior or challenging. We’ve been on the receiving end of more than a few troublemakers and/or wannabe prima donnas, so I guess that’s created a mindset of “Man the barricades, intruder spotted!” A lot of trolls can be sniffed out this way. Many others with pure motives get caught in the crossfire. An inevitable result when people shoot first, ask questions later.
I notice that when a newcomer finds him/herself confronted with suspicion, things tend to take one of three paths: #1) s/he can email a mod, understand what’s going on and make every attempt to clear the matter up in a friendly way; #2) s/he can give up and lay low for awhile, lurking to better understand the tone of the joint; or, #3) in the worst case scenario, s/he opens an outraged pit thread, leading to an escalation of the hostilities on both sides that develops into a trainwreck and banning.
FWIW, right now you’re probably somewhere between options #2 and #3.  Move even closer to the #1 side of the spectrum and I think you’ll have a much easier and more enjoyable time, dopewise.  
(Yeesh, sorry if this comes across as annoyingly academic. Online community dynamics are fascinating to me. )
