Sure. Actually you’re quite in luck to be wondering this in this particular thread, as if offers a nice overview of the situation. As you can see (particularly evidenced in the link provided) the user with the distraught Captian Picard as his avatar has an issue with self esteem which not only makes him feel under constant attack, but which also enduces a constant need to put on a show of resolve, and (literally) proclaim he will not be made to feel shamed/stupid/bullied or whatever other term suits him at the time.
He is under the impression that this somehow makes him appear strong, and that whoever he feels threatened by will simply not know how to respond to his “astounding” display of “willpower”. Because “bullies” are just softies who only deal with perpetual victim-types who don’t “stand up to them”, so they have no concept of how to deal with someone who doesn’t run away. This is why he will never leave a thread where he feels like someone else got the last word. He will continue posting long after any actual point of discussion has been lost, if to say nothing else than “nope! Still here! And still not ashamed! Now what?”
This is because he was taught somewhere along the line that if you think you’re being bullied, you simply show everyone that you’re not afraid, and the “bully” will backdown. So he makes sure to respond to every single possible post that could possibly be construed as a challenge to him because he can’t risk showing the slightest weakness, thus letting any “bully” “win.”
See he believes that by not responding he ends up appearing to have been “shamed” into submission/ silence, and because of his ingrained need to stand up to “bullies”, he simply has to respond. He can’t not respond. Not just for his own sake, but also because along with this delusion of being constantly victimized (or, I suppose he’d rather me not use that term, as I’m sure we’ll probably get a lecture about how he can’t be made to be a victim if he doesn’t want to be, it’s his choice, and you can’t make him a victim because he won’t let you blah blah blah)…
But in any case, along with this delusion he has also ingrained a guardian complex, in which he is able to make himself feel useful and important by believing he is an advocate for anyone who would-be bullied and simply doesn’t have his same strength so as not to be victimized. See by “standing up to bullies” he serves to not only protect the meek by confusing/ shocking/ shaming the “bullies” into submission with his astounding fearlessness, but he provides them with a role model, showing them what they can achieve, if only they follow his example of always making sure you reply in an Internet forum, and never let any possible direct (or even indirect) post go unaddressed.
If you’re still not clear, don’t worry. A perfect example of this will be made available soon enough…
