I'll retract the unnecessary scorn behind"feigned outrage" but not the underlying intent for the following:
"If you care to read those threads, you'll see me advising him to tread lightly as well as telling people to stop abusing him."
I've read them far more than I cared to and I find your recollection of the events a little disingenuous. You're painting the whole episode, which lasted months, with a fairly one sided brush. Several of the people you, rightly so in some cases, say were abusive to that person also stepped up early on to try and HELP him both disambiguate his problem and advise him on solutions. In many cases they were thanked with some of the most atrocious, abusive replies. The person showed a long pattern of bait and abuse on this site as well as an established history on others. You chose to ignore that, for your own reasons, and continued engaging with him until he had an epic meltdown a few weeks ago.
A meltdown you seemed to be quietly absent from while everyone else suffered from his actions. Many offensive OPs directed at the entire site that were NOT provoked. Stealing several members' contributions here and posting them to another site without permission or attribution. All the while participation on the site seemed to take a hit. There were less SoPWs, Meditations etc. The exception perhaps was a spike in PerlMonks Discussions on how to deal with the situation which just got overheated quickly. Where were you to [sic] "Advise him to tread lightly" when all this was happening?
Overall I think you mean well. It's clear from much of what you write. However in this situation I strongly feel you erred in judgement.
