An interesting point for everyone but Coolinator; most of what people think of as Stalin's "genocides" are not in fact genocides. Hundreds of thousands of people were imprisoned, executed, starved or relocated, but because Stalin was part of the team that made up what the UN considers "genocide", they omitted political views alongside race, nation, religion etc from the treatise...
So, while genocides against many ethnic peoples still went on in the USSR; against the Cossacks for example, most people killed were killed because they were an enemy of the state for political or economical reasons, rather than racial or religious ones. Interesting, huh?
Now, back to banging my head against a wall:
the deliberate and systematic extermination of a national group
By your imagination Death Panels will be responsible for killing people through lack of care. Murder, as you see it. US citizens will die. They wont, however, be targeted by "Death Panels" with aim of eliminating them as a national group.
This is completely absurd.
Are Death Panels rounding up US citizens wherever they find them and killing them? Are US citizens forced to leave their country as refugees because of persecution? Are your Death Panels actively intent on destroying the nation of the USA?
ARE THEY REALLY DOING THAT?
If the Death Panels (which are real) kill US Citizens then that's a genocide against the US population.
So if some mugger kills two people in a bungled hold up, and those two people are US citizens, is that genocide against the US population? Hell, the mugger might go out and do it again, killing three more people. Again on Sunday, killing an old lady. Genocide, right? I mean, serial killers are committing genocide against the US population. Obviously.
