When 99% of responses are "this is disgusting" or "please lock this thread", I don't see a likelihood of it turning into a "great discussion". I just don't see what positive could have come out of it, and at some point, you have to listen to your readership. I made it clear that Brendan didn't do anything wrong in posting the article, but the thread itself wasn't generating anything productive.
As for the thread started about obeying the posting rules, at times reminders are necessary. I'm not sure what about that thread you found objectionable, but I 100% stand by Edgar for starting it.
I know you meant no disrespect, and the entire staff appreciates constructive criticism, as posted here. I disagree, though, that locking threads is in any way "repressive".
