Some 'jibe' got his defenses up...but I could not find any jibes in your content. Something touched a soar spot in him and he took offence.
Stanley Sammeroff I think I would like to stop here, it was offensive. I am not debating my upbringing or yours. Perhaps in future you should consider leaving out personal jibes its a sign of desperation.
I really think the subtext of his responses is: I had a violent upbringing and I haven't turned out violent., robbed nursing homes, abused drugs etc". But he did not want to reveal these painful details.
