Sylence - so let's presume that you, sitting at your computer now, decide that it is time to post "Down with the Kind - down with Obama" in these very forums. You assume that the present make-up of WebDiplomacy players is a generally intelligent set of people, who like to espouse radical idea for the sake of interesting discussion to pass the night away, and that we are all relatively sane, comfortable people - after all, we display a level of intelligence which I would argue exceeds the average population, we have computers, etc...in other words, no reason assume any nefarious goals of the collected population.
But who is to say that someone here hasn't just suffered some dramatic life event; that their otherwise sable life hasn't just been turned upside-down. They lost their job, they just got the letter in the mail that their health coverage (which they were assured they could keep) had been cancelled, and now their spouse, the love of their life, is certain to die because she will be denied the treatment he needs...he has reached his tipping point.
He is also a hunter, mind you, with a high caliber hunting rifle that even the gun-grabbers would say is OK to own -- after all, it's a long-gun, and American tradition, and even the vocal gun-grabbers in Congress won't go after those. And by the way, his high caliber hunting rifle with the red-dot scope -- it's a sniper rifle; that's what hunting rifles are.
This gentleman also lives proximate to D.C...and as he sits here in despair, looking at the $34.75 left in his bank account, and he reads the words, "Down with the King", he realizes that his sentiment is true...that this is what he must do. After all, what else is left for him. He can't pay the next payment on his life insurance...but the money that will be paid out will save his wife's life...
...the day the President was assassinated, because a desperate hunter took a casual comment to heart, was the day the the race riots began, and Congress finally came together with enough votes to make that gun grab.
The social media was aflame within a week, and it wasn't long before the race protesters, the gun grabbers, the "liberals" that were finally seeing so many of their long-fought-for dreams being enacted by a Congress pandering to a fear-filled people were being opposed by the armed citizens who cried for their diminishing freedoms...
The blood bath that spread across the nation destabilized the economy to he point that the nations of the worlds finally turned an eye to China...the US dollar was replaced as the currency of global commerce...
...and thus the great reign of the United States came to an end, by the careless spoken free speech in a casual conversation on WebDiplomacy...
