Why it has to get personal so often, I don't know. DF didn't make me invest my money into a then .07 stock. He didn't hold a gun to my head. The ones griping the most are probably the ones making the most off the littlest moves.
Mr. Loco will break it down for you. It has the same psychological underpinnings as people watching sports and taking sides.
It starts off with rational, well researched and reasoned arguments (I've presented several here in the past). After one has made the effort to make a rational, well reasoned argument and it gets rejected ( by someone who thinks a lot is one word no less) with nonsense... well now even a patient and well educated person starts to get angry. And so it goes...
In my case, I was a true Behliever for quite some time. I fell in love with the technology, the promise of something great for the planet, etc etc. When you are betrayed by something you once loved... anyway 22K later I'm here to see how it plays out and to tell dumbassess that they are dumbassess (creatively of course).
