SD, it's simple. Anyone who gets off on bullying others is an asshole. He gets off on bullying those he thinks are newbies. Ergo he's a bully. Ergo he's an asshole.Let's dial back the venom. He's not an asshole and even if he was it wouldn't be right for you to call him one.
You didn't do anything especially wrong or worth getting worked up about by starting the thread in the AH. I think others are right, though, that it belongs in the Feedback forum, or in the Poetry forum. Poetry definitely is its own little separate corner at Literotica. I think many Literotica authors don't write or read the poetry that's posted here. I sometimes revisit my small collection of poems when I'm feeling masochistic and I want to see something that sucks.
