To barge in, refuse to be accountable for his evidence and throw a tantrum because no one accepts his argument without question. Was he layering himself in a protective cloak because he knew that he would not stand up to scrutiny and be out of his depth? Is that what all the bluster and claims of super-intelligence was about?
IMHO, almost certainly. It's the tactic of the bully...trying to use force to make others accept his argument. Most normal people when presented with this approach will recognise the trouble-maker and quietly retreat. Which allows the bully to, incorrectly, assume that his argument is in order, instead of realising that he is getting no responses because 99% of normal people will not converse with people like that.
The same thing happens in real-life. If you are walking down the street and you see a guy who's obviously drunk and being obnoxious or violent then you will cross the street to avoid an encounter, safe in the knowledge that reasoned debate will not be listened to and you are likely to end up in a scuffle for your efforts. It's left to the Police (in this case Lunar Orbit) to remove the individual to prevent him ruining the pavement (or forum) for everyone else. The only place that such people get attention is in a room full of other drunken idiots (aka GLP). The obnoxious drunk can then carry the delusion in his head that he is the smartest/wittiest/toughest baddass in town, up to the point that he finds himself pinned to the floor with the handcuffs being applied.
To a normal person, GLP is like walking sober into a room full of these drunks whilst wearing a suit of armour. You can poke and prod them and then watch them explode into a fit of incoherent rage and spittle-flecked apoplexy safe in the knowledge that a black-eye will not be the result. OK, you might get chucked out every now and then, but the room will still be full of loons.
