:AMR: You can't reject it, but it's not true. Talk about 1984.
Rather, the proposition you proffered was open ended, as I noted. Given it has no definable end point it can never be proven to be wrong or true, even if there is no evidence of it in the present and regardless of how much time has passed.
Name a democracy that is not either practicing mass murder or headed that way.
"Headed that way," has the same problem, but the word you used was genocide. Now it's a less particular phrase, "mass murder." If you're Amish that would be war. If you're against abortion, it's abortion. If you're radical enough as environmentalists go it's larger still. If you're a Buddhist...just about any civilization in just about every age.
In any event, none of it is genocide and any of the other points relies on a subjective valuation that runs into problems. No democracy is practicing mass murder. No state is taking anyone out and murdering them, or even taking their lives without due process, if then.
So maybe you're headed down the toilet a little more slowly than anyone else.
And we're back to the first problem, supra.
