Slackjawed Cow over at
the other forum has compiled screenshots of Pat's tweets from his first month on Twitter, way back in 2012.
Timeline for reference:
??? 2011 - Adrienne dumps Pat.
Aug 2011 - Pat is arrested for threatening to murder Adrienne+Jon+Annabelle.
Mar 2012 - Adrienne marries Jon.
Sep 2012 - Pat joins Twitter.
This is when Pat sets the scene for his (now-infamous) social media persona.
Bunch'a cope-tweets about Adrienne breaking his heart; brags about the half-marathon he was training for (the one he ended up cheating in); brags about his progress in becoming an author; boring geek shit and attempted jokes; letting people know that he drinks beer and has had sex.
In one of the tweets, he explains what his Twitter handle "stealthygeek" means:

So that's how
he wanted to be seen: A manly man known for manly things, that people are surprised to learn is additionally also into toy conventions and capeshit. A brave, modern defier of stereotypes. LMAO.
Another noteworthy tweet from the bunch pretty much confirms the theory that he ran that half-marathon to prove something to himself and his ex, because he very much wasn't over the divorce:

Probably also why he decided to become an author. (She'll see! I'll be rich and famous and have a well-rounded life, and then she'll be sorry for leaving me!)
Pat's now-characteristic Twitter belligerence and assholishness has not yet manifested itself in these 2012 tweets. It's a more innocent time for him. Like a crossroads, where it still looks like his life might take a positive turn.
Before he fully ingratiates himself with the pedos and Woke fanatics of the SFWA.
Before 2016 allows him to gain 50k Twitter followers by fully leaning into his abrasiveness and rabidness as a "political firebrand".
Before in 2018 he starts waging a flame war against a certain subreddit dedicated to a defunct radio show, and is cocksure that he'll win if he goes all-in.
Before in 2020 his KiwiFarms thread is created.
