Our rules about group insults are essentially this: you can insult a group of people that includes SDMB posters, like Democrats or Republicans. You can’t insult groups of posters, i.e. saying that everybody taking a contrary position in a thread has his tongue in the ass of Barack Obama (or George W. Bush, etc.).
Your warning was issued and reversed by C K Dexter Haven and I think his opinion matches mine:
Does that help?
This wasn’t a very serious infraction, no, but it was par for the course with him and I think it was obvious he was picking a fight, since he said just yesterday that I was correct to give him a note for his comment and he kept going after I gave him a few chances to handle this in a less confrontational way. He also got two warnings on July 31, and if we hadn’t already been moving toward consensus on a banning he probably would have received another warning or two yesterday for insults to another poster by private message and some other posts.
I’m speaking for just myself here, but my take was that he’d crossed over into open trolling and it was time for him to go. His behavior never changed after any warnings, so the consensus was that there was no point in suspending him and hoping he improved. Lately I think he was just stirring up shit by taking a stand against whatever he perceived to be the consensus on the board. I don’t expect anybody to read all of his posts in this 17-page World Trade Center collapse thread, but by the time he was arguing the plane that hit the Pentagon might’ve been ditched in a river or Lake Erie because everyone in America was watching TV and no one would have notice - or the previously discussed Birther thread, where he showed up on page nine asking questions that had already been answered and posting nonsense. I posted in both those threads so I thought it would be inappropriate to comment on whether he was trolling at the time, but I think that’s what he was doing. Playing devil’s advocate is always fine, but attacking the consensus on every issue just to be a nuisance because the idea of a consensus offends you is trolling.
