Shane doesn't want to post here for several reasons - he can't block people and declare himself the winner, he can't grandstand in front of his public audience of exactly nobody, he's a coward, but the main one is this: we will ask him questions that he can't answer in a way that doesn't humiliate him. His bluster and grandstanding is a very transparent mask of his deep feelings of shame and inadequacy. Staying on Twitter means that he can cherry-pick the questions he answers to avoid the difficult ones. What a pussy-ass bitch. So allow me to both ask and answer the questions Shane won't.
Q: Why does Shane lie about being a super-hacker in order to win Twitter arguments?
A: Shane is embarrassed by his life and has overwhelming feelings of failure, so he pretends to be the person that he always wanted to be. He's LARPing a Mary-Sue idealised version of himself to live, however briefly, a fantasy where his life actually turned out the way he wanted. As an example, note that he describes himself as "retired" rather than being fired and then going on disability - he's not trying to convince others so much as he is trying to convince himself, he chose to leave MS, he has control over his life. Shane is very distressed that he doesn't have control over his own life. He is someone who was convinced at a young age (possibly by his parents) that he was destined for success - that he subsequently failed is a fact that he can't bear to think about, hence the fantasy life.
Q: Why does Shane pick fights with strangers and try to intimidate and bully them?
A: Shane was bullied at school and possibly at work. He carries deep rage and resentment about this so he lashes out at people online to vent his anger. He projects the identities of the bullies who made him miserable onto the people he attacks. He also uses liberal political ideology to dehumanise his victims so that he can convince himself that he's a brave warrior fighting the ebil Nazis rather than just a fat, cowardly bully abusing cancer survivors and mocking people grieving for murdered children on Twitter to distract himself from his own inadequacies.
Q: Why does Shane block people at the end of arguments and declare himself the winner?
A: Shane is extremely insecure about his intellect. He was at pains to point out that his literal brain damage didn't affect his "cognition". The idea that Shane Is Very Smart is fundamental to his ego, his self-conception and his self-esteem. His way of coping with failure includes the idea that "my body let me down, but I'm still a super-genius". He tells himself this constantly to reassure himself of his superiority, it's also why he's so entitled and condescending. Sadly, Shane isn't really very smart. A lot of his behaviour since he came on KF's radar has been extraordinarily stupid, blundering into self-own after self-own. As we saw in his last argument, when he started to lose he resorted to ad-hominem attacks, strawmanning and just hurling insults in lieu of being able to counter the points the other guy made. Shane convinced himself that he didn't need to deploy his vast intellect against a Nazi Chud, not that he didn't have an answer. The idea that he may be of, at best, average intelligence, terrifies him. We're talking real fear. He couldn't get away with the tactics he uses on Twitter here, he knows that, and he really frightened of not being able to win arguments here. Not so much because he'd be embarrassed or that the evil Kiwi TERFs might win, but because it will hurt his ability to lie to himself and maintain the illusions that are at the heart of his self-esteem.
Q: Why does Shane not stand up for his partner when her appearance was mocked?
A: Fundamentally Shane is a coward who only cares about himself. He doesn't respect his girlfriend enough to defend her. His wife left him, after all, he thinks that women are disloyal bitches who don't appreciate what a genius he is. Shane lost his virginity late in life, probably to the woman he married (who subsequently walked out). He is very insecure about his sexual performance, hence it is something he lies and brags about (Daddy Cum Cannon indeed). I'm willing to bet that he flirted with Incel ideologies before he finally lost his virginity, and they've never quite left him. He has nothing but contempt for his girlfriend - she willingly had sex with Shane Nokes after all, she can't be a very classy broad to do something that debased. She's all he can get, he feels like he's feeding off scraps from the feasting table when he feels entitled to the prime cuts. But no, he has to make do with the gunt, and that makes him rage deep inside like the Incel he is at heart. When we point that out, he has no comeback because he believes that too.
Q: Why does Shane pretend not to be bothered by this thread despite following it obsessively and announcing his plans to flag down Null's stream because it might make fun of him?
Shane desperately needs to feel in control of his life, because his illness and personal inadequacies took that control away from him and deprived him of the destiny that he felt (and still feels) he was entitled to. That's why he employs the "puppetmaster defence", desperately insisting that having Kiwis and OnA humiliate him over and over is part of his master plan. He's not owned! He planned this! Ultimately, this goes back to the common theme between all these answers - Shane doesn't tell these lies to convince others, he tells them to convince himself. If he says he's not bothered by this thread, then that must be true - look, it's written down now, Shane's word is law and if Shane says he's not bothered then that is true - at least for Shane - and that way he can ignore the mountain of evidence that says otherwise. That's why he won't come here - he can't control the narrative, he can't choose what questions to answer, and someone will say something that pierces his own illusions about himself.
Shane is fundamentally a fantasist. Someone who plays pretend about their life to avoid dealing with feelings of inadequacy, loss and failure. That alone wouldn't make him a lolcow, but what pushes him over the line from someone you could feel some degree of sympathy for to someone you can't, is that he tries to impose his fantasies on others. His vicious bullying, lying and intimidation of strangers on the internet is what people truly despise about him, but he's convinced himself (or at least desperately tries to convince himself) that he's justified in doing these things. But he knows he isn't, deep down. He knows what a piece of shit he is, and if he came here that would be exposed. That's what he's afraid of - confronting the truth about himself that he has obfuscated with lies for years.
His lies aren't really to convince other people - they're to convince himself.
Yo Shane, if I'm wrong about these, come here and prove otherwise.
Pussy.
