Not your fault that they sent the wrong guy....what else could you think? You reasoned on what was presented to you...a fat long haired loser...and I daresay he knew his audience because he had to have been there earlier in his own career and I'd blame his command for sending him because they surely knew how he'd be received.
I think that Herc guy was here for awhile. I haven't seen him around anymore, so maybe he's continued on with his blogging/editorial job.
