How far back is "historically"?
Since a couple of years ago when Sargon & his lapdogs was trying to woo Jim into Liberalistism, Jim's response was the catalyst of the lolcow he has become today.
While this might be stretching it, I'm starting to think that Jim was never that thick skinned to begin with, as far as I can remember most of the time Jim was in some call Jim would only ask questions and then leave and the fewer instances of him being in a debate/discussion, it was usually against low hanging fruits.
since historically, his explanation for his poor performance in his debate/discussion with Destiny was (paraphrasing):
"It went to shit, we both more or less lost, but Destiny, right after the debate fucking starting drawing on his gay ass draw board about some shit."
That screams in my ear: hurt.
The part about him not giving out his info online, I genuinely think that's more due to him coming from the early days of the internet, where those outside the norm knew never to post anything about yourself.
