I doubt the trheats were directed at him for his belief as much as for his nasty and provacative insults, which probably instigated the whole thing. The writer was obviously out looking for a fight, and pushing peoples buttons until he got one. Here are just the first two paragraphs of his post:
"Of all the incredibly stupid things people do to their CPUs, including overclocking them until they are hot enough to melt steel, the single most imbecilic modification has to be lapping. Using absurdly skewed logic and completely unsupported data, lappers believe that by physically grinding down the surfaces of their CPUs to make them flatter and gain better contact with the similarly lapped surfaces of their heatsink fan cooler assembly they will lower their operating temperatures up to 20 degrees C.
The miraculous advantages of lapping are evangelized by the same sort of online loonies who believe that Microsoft and AOL are giving away merchandise and cash just for forwarding an email message, three triangulated cell phones can pop popcorn kernels, and that Barack Obama was sworn into his Senatorial office with his hand on the Koran."
So in the first two paragrapghs he calls overclockers incredibly stupid. He then refers to lappers as imbecilic, absurdly skewed thinkers, and online loonies. After he pushes people to the point of threatening him, he suddenly takes the poise of a defenseless victim whose only option to defend his safety is to call the police.
Certainly, the death trhreats were over reactions and innapropriate, but this guy looks to have manipulated the situation into exactly the circumstances he wanted in order to feed his need for attention and compensate for a badly wounded ego.
