What do you think of "internet tough guys"?

Ooooh. Nice question. Nothing more appealing than some douche throwing random insults and threats of bodily harm all over the place. It reflects on their own insecurity, I suspect such people have been bullied or abused and use the internet to project some sort of control over their feelings. It really isn't very brave, bright or classy. I think it also reveals much about their level of education and background.
